Experimental investigations of the electronic, structural, and dynamic properties of clean and adsorbate-covered metal and semiconductor surfaces and thin films using a variety of surface probes.
Experimental techniques include X-ray Standing Waves (XSW), Angle-Resolved Ultraviolet Photoemission Spectroscopy (ARUPS), Inverse Photoemission Spectroscopy (IPES), High Resolution Core Level Spectroscopy (HRCLS), Auger Electron Spectroscopy (AES), Low Energy Electron Diffraction (LEED), Atomic Force Microscopy (AFM), and Rutherford BackScattering Spectrometry (RBS).
