Abstract

This report compiles papers concerning especially recent developments in work function theory and work function measurements, which were given at a round table conference about surface phenomena in thermionic research, arranged by the 'Deutsche Forschungs- und Versuchsanstalt fuer Luft- und Raumfahrt' in Stuttgart on Nov. 20 and Dec. 1, 1972. 9 papers are printed completely, 4 others in form of a summary. Two of them concern the work function of uncovered surfaces, 2 others show the influence of adsorbed electropositive elements (Cs, Sr) on work function. In 4 papers the coadsorption of electropositive (Cs, Sr, resp. Ba) and electronegative (O {sub 2}) elements and their influence on work function of different surfaces are discussed. Finally a paper is added, describing the development of Sr-Cs-alloys, which are of interest for the generation of the atmosphere of a Sr-Cs-converter by means of one single reservoir. (auth)
