Popis:	Electron beam stimulated micro- and macroscopic phenomena are reported for CdS surfaces irradiated with a two keV electron beam. Microscopic effects - confined strictly to the irradiated area - were observed in the presence of water vapor of a partial pressure as low as 10 -9 Torr leading to: changes in surface composition, decrease in work function, and striking enhancement of the surface recombination velocity. Macroscopic effects were associated with irreversible changes in the electronic properties of the entire surface rather than of the irradiated regions only.
