Photoemission, Vibrational and Stimulated Desorption Studies of Metal-Semiconductor Interfaces and of Chemisorbed Atoms and Molecules.
Abstract
This program has produced in recent years a number of fundamental results on the microscopic properties of metal-semiconductor interfaces and on the mechanism of photon stimulated desorption. Both areas of research are of fundamental interest in condensed matter physics. Furthermore they have important applications in technology. The microscopic metal-semiconductor interface properties are directly related to the behavior and performance of the Schottky barrier, one of the building blocks of modern solid-state devices. This program investigates the formation of metal-semiconductor interfaces with some of the most powerful surface-science experimental probes: photoemission spectroscopy with synchrotron radiation, Auger spectroscopy, low-energy electron defraction in high-resolution electron energy loss surface vibrational spectroscopy. The stimulated desorption process is potentially a good probe of the chemical properties of absorbed species, e.g. in catalytic systems.
