Annual Summary Report on ONR Contract N00014-77-C-0018.
Abstract
Work carried out during this period has consisted of a detailed study of the adsorption, desorption and thermodynamics properties of CO on W(110) covered with one or more CU monolayers. The most detailed measurements were made for W(110)/Cu1. Preliminary equilibrium measurements were also made for W(110)/Cu6. Some work function measurements for CO adsorption were also carried out on intermediate layer thicknesses. The principal tools in this phase of the work were thermal desorption, using a quadrupole mass spectrometer as detector for isothermal and temperature ramped measurements, and work function measurements using the newly constructed and high accurate, reproducible (< 1 meV) and fast (< 0.1 sec response time) Kelvin probe for work function measurements. The latter were used to determine sticking coefficients, coverage vs. temperature rise (i.e. ramped desorption giving not the rate but the remaining coverage) and adsorption isobars, i.e. coverage as function of surface temperature for a series of constant CO pressures.
