STUDIES OF GAS-SURFACE INTERACTIONS AT THE (100) CRYSTAL FACE OF PLATINUM BY MOLECULAR BEAM SCATTERING, LOW ENERGY ELECTRON DIFFRACTION, AND AUGER ELECTRON SPECTROSCOPY

摘要

An apparatus has been constructed to investigate energy transfer and chemical reactions at the gas-surface interface and the mechanisms of gas-solid interactions. Low energy electron diffraction and Auger electron spectroscopy were employed to characterize the surface structure and the chemical composition of the solid and the adsorbed layer. A thermal molecular beam provided gaseous species at a predetermined angle of incidence with respect to the surface normal and a quadrupole mass spectrometer detected the angular distributions of the incident and scattered beams.
