A systematic study of polarized electron emission from strained GaAs/GaAsP superlattice photocathodes
T. Maruyama, D. -A. Luh, A. Brachmann +8
Spin-polarized electron photoemission has been studied for GaAs/GaAsP strained superlattice cathodes grown by gas-source molecular beam epitaxy. The superlattice struct…

Atomic Hydrogen Cleaning of Polarized GaAs Photocathodes
T. Maruyama, D. -A. Luh, A. Brachmann +6
Atomic hydrogen cleaning followed by heat cleaning at 450C was used to prepare negative-electron-affinity GaAs photocathodes. When hydrogen ions were eliminated, quantum ef…
