Solid State Physics—Experiments, Data Analysis, and Modeling

1. (1) Core-Level Photoemission.  This project is aimed at understanding the formation and growth of layered metallic systems.  We are currently analyzing photoemission data from a variety of metals layers grown on tungsten surfaces.
   

2. (2) Vibrational Dynamics at Surfaces.  We seek to understand vibrations at surfaces and how those vibrations differ from inside the material (bulk vibrations).
   

3. (3) Temperature Dependence of Semiconductor Energy Gaps.  We are currently exploring a new method of analyzing energy-gap temperature dependence.
   

4. (4) Ultrafast Spectroscopy of Semiconductors.  This research explores the femtosecond excitation and    subsequent decay of carriers in semiconductors. GaAs and related materials are currently under study.
   

Skills:  Experience in experimentation and/or computer modeling is useful, but the necessary skills can be acquired during the course of the project.
