Abstract

The degradation of CsI thin film photocathodes (PCs) under The degradation of CsI thin film photocathodes (PCs) under Ultraviolet (UV) irradiation has been investigated by measuring the Ultraviolet (UV) irradiation has been investigated by measuring the photocurrent as well as the absolute Quantum Efficiency (QE) as a photocurrent as well as the absolute Quantum Efficiency (QE) as a

function of the accumulated charge density. function of the accumulated charge density. Atomic Force Microscopy (AFM) and UV Photoemission Electron Atomic Force Microscopy (AFM) and UV Photoemission Electron

Microscopy (PEEM) have been employed to study the surface Microscopy (PEEM) have been employed to study the surface morphology and the local QE of polycrystalline CsI thin films and morphology and the local QE of polycrystalline CsI thin films and

their transformation due to UV irradiation. their transformation due to UV irradiation. The photo-emissive properties of CsI PCs, together with their The photo-emissive properties of CsI PCs, together with their

surface morphology, have been found to be strongly affected by the surface morphology, have been found to be strongly affected by the UV photon ageing. UV photon ageing.
