| Abstract: | In this paper, the principle of the field-assisted photocathode InP(substrate)/ InGaAsP(photon absorber layer)/InP(emitter layer)/Ag/CsO, responsed to 1.3μm was . described briefly. Its energy band was calculated. We attained, the quantitative relationship among the barrier haight between InGaAsP photon absorber layer and InP emitter layer, doping level, thickness of InP emitter layer, the InGaAsP/InP hetero-junction composition grading distance, voltage of reversed bias and the width of depleting layer, basised on this relationship. All.parameters of photocathode are discussed. |
