N2 - Temperature and optical power density dependences of the photovoltage at a p-GaN(Cs) photocathode surface were measured in the temperature range 90-295 K. The study demonstrated that band bending at the p-GaN(Cs) photocathode surface can be reduced by ∼ 0.5 eV without modifying the surface atomic structure. The surface photovoltage impact on the p-GaN(Cs) photocathode quantum efficiency and photoelectron energy distributions was analyzed.
