Photoemission study of Cs–NF[sub 3] activated GaAs(100) negative electron affinity photocathodes
Zhi Liu, Yun Sun, Samuel Peterson, and Piero Pianetta
GaAs based negative electron affinity photocathodes activated with Cs and NF are used as polarized electron sources for linear accelerators. It is generally believed that the activation layer consists of CsF. The activation layers of CsNF on GaAs photocathodes are herein investigated using synchrotr ... [Appl. Phys.
