Enhancement of Spin-Polarized Electron Emission from Strain-Compensated AlInGaAs-GaAsP Superlattices
Resonance enhancement of the quantum efficiency of new polarized electron
photocathodes based on a short-period strain-compensated AlInGaAs/GaAsP
superlattice structure is reported. The superlattice is a part of an integrated
Fabry-Perot optical cavity. We demonstrate that the Fabry-Perot resonator enhances
quantum efficiency by up to a factor 10 in the wavelength region of the main
polarization maximum. The high structural quality implied by these results
to the very promising application of these photocathodes for spin-polarized
