Abstract

Desorption Induced by Electronic Transitions (DIET) is a primary mechanism through which energy deposited by electrons and photons in the surfaces of ionic insulators is dissipated.¹ Studies of Photon-Stimulated Desorption (PSD) at ultraviolet wavelengths are important from a fundamental point of view because photons deposit energy but not free charge in dielectric materials. PSD also has practical consequences in problems as diverse as optical damage in high-power lasers, non-destructive surface analysis and uv photolithography.
