Cs-O_{2}-Li as enhanced NEA surface layer with increased lifetime for GaAs photocathodes
GaAs-based photocathodes are the only viable source capable of providing spin-polarized electrons for accelerator applications. This type of photocathode requires a thin surface layer, in order to achieve negative electron affinity (NEA) for efficient photoemission. However, this layer is vulnerable...
