Abstract
A high-gradient-doping technique is applied to strained polarized photocathodes. A 5.0–7.5 nm p-type surface layer doped to 5×1019 cm−3 is found sufficient to overcome the surface charge limit while maintaining high beam polarization. This technique can be employed to meet the charge requirements of the Next Linear Collider with a polarization approaching 80%.
