Abstract
Higher beam currents and brightness are desired, therefore new photocathodes with higher QE are required.
p-type GaN can produce a negative electron affinity (NEA) surface when cesium is deposited on it.
A thermal cleaning under vacuum was carried out to achieve an atomically clean surface before the Cs deposition.
Keywords: p-GaN photocathode; XPS surface studies; semiconductor; surface cleaning
