FEM study of palladium and molybdenum clusters on an alumina covered field emitter

  • Published:
Czechoslovak Journal of Physics Aims and scope

Abstract

Palladium and molybdenum polycrystalline layers (clusters) have been deposited in a stainless steel UHV system onto a layer of alumina (Al2O3). This layer has been prepared by high temperature oxidation of an aluminium layer. The interaction of this system with nitrogen has been investigated at room temperature by an FEM technique. Under these conditions nitrogen spillover from molybdenum to palladium has been observed.
