STUDY OF MATERIALS FOR THERMIONIC CONVERTERS

Abstract

This program has been concerned with an examination of the fundamental properties of materials from a solid-state physics and chemistry point of view. In this report particular attention has been laid to the factors which influence the work function and its temperature coefficient for metals, semiconductors, and insulators. Considerable emphasis was placed upon the surface properties of solids and upon the manner in which the surface barriers and adsorbed monolayers affect the total work functions. Both internal and external work functions were considered. Tables were compiled of published adsorption data% and of properties of certain photoemitters which are potentially useful as low work function collectors in thermionic converters.
