The Department of Applied Physical Sciences at the University of North Carolina at Chapel Hill is an interdisciplinary graduate program that includes faculty from chemistry, mathematics, physics and astronomy, chemistry, and various departments across the university to engage in research and training in applications of the physical sciences. The primary areas of emphasis in the program are optical and electronic materials, nanomaterials, polymers, and biomaterials. Students pursuing M.S. and Ph.D. degrees in materials science begin their studies with a core curriculum covering the fundamentals of materials, including their structures, surfaces, fabrication, thermodynamics, and materials science laboratory techniques. They continue with elective courses offered by the curriculum or the other departments as appropriate to their area of research concentration. Graduate students engage in research under the supervision of one of the participating materials science faculty in the Department of Applied Physical Sciences.

Research Interests

The four areas of research emphasized in the program are electronic, nano, polymer, and biomaterials. These four areas are not discrete, however, as research projects in electronic polymers, nonlinear optics of polypeptides on surfaces, liquid crystals, and wear in polyethylene artificial joints demonstrate. Individual faculty members may have research interests in more than one of the primary areas, and may collaborate with others to address all four. For detailed information on the graduate program, please contact the graduate student coordinator at 919-962-4703 or g-admit-apsc@unc.edu.

Degree Requirements

The Ph.D. degree requirements include completion of a suitable set of courses, cumulative written comprehensive exams, a preliminary doctoral oral exam, an original research project culminating in a dissertation, and a final oral exam. The M.S. degree requirements include completion of a suitable set of courses, cumulative written comprehensive exams, a research project, and a final oral exam. The general regulations of The Graduate School govern credit hour, residency, and examination requirements.

Courses

All graduate students must pass the following courses or appropriate ones approved by the curriculum, or must have passed their equivalents elsewhere: APPL 470, APPL 473, and MTSC 615, 720, 730, and 735. Each student also takes additional courses offered by the curriculum or participating departments, as appropriate for his or her area of study.

Comprehensive Exam

M.S. students must pass three core exams and one specialty exam. Ph.D. students must pass four core exams and two specialty comprehensive exams. Topics for the specialty exams will be research areas represented in the materials science program at UNC–Chapel Hill; core exams cover the fundamental knowledge of materials science. All students are required to complete the comprehensive exam by the end of their second year.

Preliminary Doctoral Oral Exam

Students are required to select a research adviser during the first year in graduate school and a thesis committee before they take the preliminary doctoral exam. To pass the preliminary doctoral oral exam, students must present and successfully defend their Ph.D. research proposal to the dissertation committee by the end of the third year.

Facilities and Equipment

Students and faculty in the curriculum have access to the following central facilities located in various departments: NMR (2), computer modeling and computer graphics, confocal microscopy, electron microscopy (SEM, TEM, and STEM), FIB, glass shop, machine shop (2), laser lab, mechanical testing, mass spectroscopy, and X-ray diffraction. In addition, a variety of equipment is located in individual research laboratories. This includes equipment for thermal analysis; polymer synthesis; FTIR, UV-Vis, Raman, and photoluminescence spectroscopy; ellipsometry; CVD; MBE; thermal oxidation; AFM; electrical measurements; nonlinear optics; and low temperatures and high pressures. Facilities at North Carolina State University in Raleigh and MCNC in Research Triangle Park are also available.

Fellowships and Assistantships

Teaching assistantships are available to qualified graduate students. The duties of teaching assistants include teaching laboratory sections, assisting in the supervision of advanced laboratories, teaching recitation sections, and grading papers. Summer support is generally available. Research assistantships are also offered.
