Abstract
The Cs content of GaAs(Cs) and GaAs(Cs–O) photocathodes was determined by direct chemical analysis. The surface films were found to be of monolayer dimension. From this result, it is concluded that the effect of these films on electron emission is probably not associated with the bulk properties of cesium oxide.Keywords
