Abstract:

The field electron microscope was used for the precise determination of thermodynamic and electrical properties of Sr adsorbed on W. For Sr coverages above theta nearly equal to 0.70 the Sr adlayer exhibits bulk properties. Below theta nearly equal to 0.20 Sr is probably adsorbed in the ionic state. Between theta nearly equal to 0.20 and theta nearly equal to 0.70 there is a mixture of ionic surface properties and bulk properties in the adsorbed Sr. At a characteristic, or isokinetic temperature of 1350K the rate of thermal desorption of Sr from W is independent of Sr coverage theta.
