AbstractSemiconductor photocathodes, particularly those produced with thin films and heterostructures, are promising candidates of high brightness electron sources. It is also well-known that electron beam brightness increases with the photocathode gun’s operating gradient. Combining both heterostructure semiconductor photocathode and cyro-cooled high-gradient photocathode gun may improve electron sources for many applications. However, effects of the high field gradient on the semiconductor photocathode need to be understood in order to preserve and optimize the quality of the emitted photo-electron beams, which can be done with from detailed simulation study and theoretical analysis. In this work, we apply Monte-Carlo method to study high field transport and emission from semiconductor photocathodes such as Cs2Te. The results will be used to inform a theoretical transport model based on the moments method and the cathode development for the CARIE project at LANL.
