The Department of Materials was conceptualized and built under two basic guidelines: to educate graduate students in advanced materials and to introduce them to novel ways of doing research in a collaborative, multidisciplinary environment. Advancing materials technology today - either by creating new materials or improving the properties of existing ones - requires a synthesis of expertise from the classic materials fields of metallurgy, ceramics, and polymer science, and such fundamental disciplines as applied mechanics, chemistry, biology, and solid-state physics. Since no individual has the necessary breadth and depth of knowledge in all these areas, solving advanced materials problems demands the integrated efforts of scientists and engineers with different backgrounds and skills in a research team. The department has effectively transferred the research team concept, which is the operating mode of the high technology industry, into an academic environment.
The department has major research groups working on a wide range of advanced inorganic and organic materials, including advanced structural alloys, ceramics and polymers; high performance composites; thermal barrier coatings and engineered surfaces; organic, inorganic and hybrid semiconductor and photonic material systems; catalysts and porous materials, magnetic, ferroelectric and multiferroic materials; biomaterials and biosurfaces, including biomedically relevant systems; colloids, gels and other complex fluids; lasers, LEDs and optoelectronic devices; packaging systems; microscale engineered systems, including MEMS. The groups are typically multidisciplinary involving faculty, postdoctoral researchers and graduate students working on the synthesis and processing, structural characterization, property evaluation, microstructure-property relationships and mathematical models relating micromechanisms to macroscopic behavior. The department has close collaborations with, and a number of faculty have joint appointments in, the Departments of Mechanical Engineering (mechanics and design), Chemical Engineering (fluids and environmental effects), Electrical and Computer Engineering (electronic devices), Physics, Chemistry and Biochemistry, and the BMSE Program.
Five-Year Bachelor of Science Engineering/Master of Science Materials Program
A program combining a bachelor of science in chemical, electrical, or mechanical engineering with a master of science degree in materials provides an opportunity for outstanding undergraduates to earn both degrees in five years. Additional information about this program is available from the College of Engineering. Interested students should inform the Office of Undergraduate Studies in the College of Engineering of their intention to pursue this program in the beginning of the spring quarter of their sophomore year. Transfer students interested in the combined degree program should contact the undergraduate advising office at the earliest opportunity. In addition to fulfilling undergraduate degree requirements, B.S./M.S. degree candidates must meet Graduate Division degree requirements, including university requirements for residence and units of coursework as described in the section "Graduate Education at UCSB."
Graduate Program
In addition to departmental requirements, program applicants and candidates for graduate degrees must fulfill University requirements described in the section "Graduate Education at UCSB."
Admission
Undergraduate preparation for the materials M.S./Ph.D. includes a degree in engineering, physical sciences, or mathematics. However, the breadth of the materials field requires that flexibility be built into the undergraduate educational requirements. Upper-division courses in several of the following topics are expected:
- mathematics - 24 units in advanced calculus, ordinary differential equations, special functions and complex variable theory,
- engineering thermodynamics - 9 units,
- solid state physics - 9 units,
- physical chemistry - 12 units,
- materials science - 12 units in mechanical properties, electronic properties, structure, processing,
- electronics - 12 units,
- mechanics - 9 units in advanced strength of materials, elasticity, and structures.
Incoming students are not expected to meet all upper-division requirements, but must satisfy the requirements in mathematics and at least two other areas representing about one full year of undergraduate study. The areas that should be covered will depend on the student’s chosen graduate field of study within materials. Some deficiencies can be satisfied during the first year of graduate study by taking upper-division undergraduate courses in the new area of specialization.
Students with a B.S. degree (having a 3.2 minimum grade-point average) are eligible to be admitted to M.S./Ph.D. status and those with an M.S. degree (having a 3.5 minimum grade-point average) are eligible to be admitted to Ph.D. status. The department gives priority for admission to students who are interested in academics and high quality research. Admission is available for all quarters, with no departmental deadlines beyond those of the Graduate Division. Satisfactory performance in the Graduate Record Examination is required. Applicants whose native language is not English must receive a score of at least 250 on the computer-based Test of English as a Foreign Language (TOEFL) or complete the International English Language Testing System (IELTS) prior to admission to UCSB. Requests for exceptions to this requirement will be considered for those students who have completed an undergraduate or graduate education at an institution whose primary language of instruction is English.
Master of Science -- Materials
Students wishing to terminate their studies with an M.S. must do so under Plan 1. Students in the B.S./M.S. program follow Plan 2. The M.S. degree program introduces students to the knowledge needed to proceed to candidacy as well as to the nature of research and the discipline of independent work. Students wishing to continue on for the Ph.D. must achieve a 3.5 grade-point average in their coursework and pass the preliminary examination discussed below in the “Doctor of Philosophy" section.
Plan 1. Students in this plan are required to (1) complete 42 units, of which 24 units would be approved 200-level courses, 6 units of seminars, and 12 units of thesis research, and (2) submit an acceptable thesis based on original research. The expected time for completion is two years.
Plan 2. Students in this plan must be participants in the five-year B.S./M.S. program and are required to (1) complete 42 units approved by the department, including no fewer than 24 units of coursework numbered 200-299, no fewer than 3 and no more than 9 units of independent studies (Materials 596), and (2) submit an acceptable engineering report based on their independent studies. Further details are available from the Department of Materials Graduate Affairs Office or the Graduate Advisor.
Doctor of Philosophy -- Materials
The Department of Materials offers a program leading to a Ph.D. degree with specializations in the following major areas: electronic materials (semiconductors, superconductors, quantum structures and optoelectronic materials); inorganic materials (ferroelectrics, photonic and magnetic materials, and zeolite molecular sieves); macro/biomolecular materials (self-assembling polymers, biopolymers, biomembranes, and conducting polymers); and structural materials (metals, ceramics, composites, and coatings, including mechanics of materials). The curriculum in each area has the flexibility needed to provide multidisciplinary educational opportunities in the field of advanced materials. Incoming students are expected to design a tentative program of study suitable to their interests and research field with the assistance of their advisor and submit it for approval to the Graduate Affairs Committee within the first two quarters of residence. Each study program consists of a specified course sequence with emphasis on lectures, laboratory experience, and seminars.
Degree Requirements
In developing an appropriate, interdisciplinary course of study, doctoral students are expected to take all the available courses in their major area of interest as well as courses designed to broaden their knowledge of other materials. It is expected that individual students will develop their study plans in conjunction with their faculty advisors, and that the courses will be selected from the main sequence of courses (offered every year) from the four principal areas of emphasis in the department plus general courses as well as more specialized courses offered on a less frequent basis. The study plan must be approved by the faculty advisor and the department Graduate Affairs Committee. It may be modified during the course of the student’s program.
Students admitted with a bachelor’s degree are required to complete a minimum of 72 units of academic work distributed as follows: 42 units of 200-level courses, 15 units of seminars and/or independent studies, and 15 units of thesis research. All Ph.D. students are required to complete a series of core courses (MATRL 200A-B-C). In preparation for more advanced and specialized courses within their area of specialization, students are strongly encouraged to complete these courses during their first year of study.
Students are required to serve as teaching assistants for at least one quarter while in residence at UCSB, in either materials courses offered to undergraduate students or those departments providing courses consistent with the student’s undergraduate background.
Students entering with an M.S. degree may petition to waive certain unit requirements for the Ph.D. (up to 15 units of 200-level courses) deemed to have been fulfilled by Master’s studies elsewhere. There is no foreign language requirement in either the M.S. or Ph.D. program. Doctoral students, however, are encouraged to become proficient in one or more foreign languages relevant to the technical literature in their fields. Students have the opportunity to take upper-division undergraduate courses, for which they have the necessary prerequisite qualifications, as preparation for the graduate program. Up to 8 units of such courses can be taken for credit toward the 200-level course requirements.
A preliminary examination is required for continuation in the Ph.D. program. The examination is administered one year after the student’s entrance into the program. The examination committee consists of three faculty members from the student’s major field, including the student’s advisor. At least two of the members must be ladder faculty with a non-zero percent appointment in Materials.
Students must pass an oral qualifying examination covering a dissertation proposal based on original research. The examination is administered two years after the student’s entrance into the program. Prerequisites for the examination include successful completion of the preliminary examination, completion of the core courses (200A, B, C) with a minimum of B in each one of them, and a minimum 3.5 GPA in the graduate program. The examination committee consists of at least four faculty: at least three having more than a 0% appointment in the Materials Department and at least one with no more than a zero percent appointment in the Materials Department. One member of the committee, other than the advisor, serves as the committee chair. Upon passing this examination, students advance to candidacy for the Ph.D. The examination committee typically becomes the dissertation committee. Subsequent to advancement to candidacy, students are required to report their progress to their dissertation committee at least once a year.
Students conduct original research under the supervision of their research advisor(s) and prepare a dissertation. Students submit their final draft to the dissertation committee and to the department chair. The committee ascertains the suitability of the draft. Candidates are then responsible for amendments to the dissertation based on the committee recommendations. When the dissertation is approved by the committee, the candidate presents a formal defense of the dissertation in a public seminar. Students are expected to complete a Ph.D. within five years after entry at the B.S. level and three years after M.S. level entry.
