Abstract

Charging of insulator surfaces under low energy electron impact is related to the gradual change of the secondary emission yield. The state of the surface can be characterized by the threshold voltage, E//c below this charging to cathode potential occurs. Studies of NaCl crystals cleaved, annealed and electron irradiated at room or liquid nitrogen temperature are reported. The variation of E//c with irradiation time exhibits a characteristic curve, containing a nearly horizontal section, followed by steep rise. A simplified model is proposed for the change of E//c. The model is considering the surface segregation of Na, production and migration of defects, vacancies, scattering and capture of secondary electrons on defects.
