34. Recent Advances in Superlattice GaAs/GaAsP Photocathodes for Spin-Polarized Electron Sources

Dr Jyoti Biswas

Abstract:

Photocathodes based on GaAs and other III–V semiconductors are capable of producing highly spin-polarized electron beams. GaAs/GaAsP superlattice photocathodes exhibit high spin polarization; however, the quantum efficiency (QE) is limited to less than 1%. To increase the QE, GaAs/GaAsP superlattice photocathodes with a Distributed Bragg Reflector (DBR) are usually used...
