Research:

Surface Science:
Characterization of thin metal films grown epitaxially and/or amorphously on a variety of substrates; scanning probe microscopy; programmed thermal desorption; electron diffraction; metal-insulator-metal tunnel junction; vibrational spectroscopy.

A major area of research in surface science is thin film growth and characterization. Of particular interest is the onset of epitaxial growth and critical island size for metal films. Four vacuum chambers are available for film growth. Presently growth characterization is limited to scanning probe microscopy (one ambient STM/AFM and one UHV STM), reverse-view electron diffraction, and measurements of electronic properties such as Hall voltages and magnetoresistance. Related to the thin film work is the study of mechanisms by which molecular compounds adsorb on the surface of highly reflective metal films. Chemical compounds of particular interest are those related to adhesion or lubrication. Techniques used for these studies are inelastic electron tunneling spectroscopy (IETS), infrared (IR) spectroscopy, and programmed thermal desorption (PTD) spectroscopy.
