Abstract
Photovoltage and photoemission experiments have shown that the GaAsP cold cathode negative electron affinity condition was inhibited by a surface defect state. Operationally, the NEA condition was further restricted by cesium coating of nonsemiconductor surfaces resulting in a reduction of band bending at the p surface, unless a negative potential of 50-70 V was applied to the cathode
