Abstract
Resonance enhancement of the quantum yield of polarized electrons from photocathodes based on strained short-period semiconductor superlattices is studied. The superlattice is a constituent of a Fabry-Perot optical cavity formed by the outer surface of the photocathode and the distributed Bragg reflector. An increase in the quantum yield by an order of magnitude is observed in the wavelength region corresponding to the maximum degree of polarization of photoemission.
