(1) Experimental project. Analyze the growth of crystallites as they emerge from the amorphous phase of a precursor film at a series of different temperatures and calculate the activation eergy. Question: Is the activation energy obtained form the interface velocity of a single crystallite the same as the activation energy derived from a total phase fraction analysis? Or do the two processes involve different mecahnisms? The main project involves image analysis of already-collected, but there will be opportunities for hands-on acquisition of your own data.
(2) Experimental project. Characterize thin-film materials by optical reflection and transmission, ellipsometry and Raman spectroscopy. Find the semiconductor band gap and complex refractive index of materials that are relevant to solar cells, energy storage, catalysis, etc. (1-2 students)
(3) Experimental project. Measure X-ray absorption in manganese and try to solve a long-standing anomaly in a Modern Physics Laboratory experiment.
Undergrads attend weekly group meetings and work with the lead graduate student on a project. They have their own projects, but are expected to collaborate extensively to contribute to the group effort.
Interested students should contact Janet Tate at tate at physics.oregonstate.edu and request a meeting. You should also attach a copy of your resume or CV to the email so I know a bit about your background. No special qualifications are necessary to apply, but it helps to understand your interests, motivation and experience. Tell me what classes you've taken and why you're interested in the projects.
