THE KINETICS OF Sr ON W BY DC FIELD ELECTRON MICROSCOPY

Abstract

Stable states of Sr on W identified during deposition were also observed in migration and desorption experiments. These studies suggest that the adsorbate consists of a strongly bound layer next to the W substrate and a loosely bound outer layer. Experiments with SrO on W failed to show whether or not Sr influenced transition from one Sr-O-W complex to another for tip temperatures below 1150 K.
