Photoelectron energy distribution of Cs3Sb

Photoelectron energy distribution of Cs3Sb

Photoelectron energy distributions from semitransparent Cs3Sb photocathodes have been measured using a parallel plate analyzer. Argon–ion and helium–neon lasers are used as light sources. The energy spread, defined as the full width at half-maximum of the distribution, is found to depend on the inci...

Zusammenfassung:Photoelectron energy distributions from semitransparent Cs3Sb photocathodes have been measured using a parallel plate analyzer. Argon–ion and helium–neon lasers are used as light sources. The energy spread, defined as the full width at half-maximum of the distribution, is found to depend on the incident photo energy Eλ according to the empirical relation, ΔE(eV)=0.25 Eλ (eV)−0.39. It is shown that the photoelectron energy distributions vary with the emitted current density.
