The In Situ Observation of Epitaxial Diamond Thin Film Nucleation and Growth Using Emission Electron Microscopy

Abstract

A method for activation of high resistivity,(100) texture CVD diamond films with gold, to improve low field electron emission is described. A model based on the dielectric breakdown of the diamond film is proposed and a test experiment, which consists of heating the gold layer to a point where the gold forms sub-micron sphereoids on the diamond surface, is described which supports the model. The deposition of carbon and sulfur on Mo(310) is characterized with scanning Auger Microscopy. Correlation between Photoelectron emission Microscopy, scanning Auger Microscopy and Auger spectroscopy can be made, so that individual features in PEEM and SAM images can be identified by elemental composition.
