Description

Data are presented from a study of changes in the spectra of surface states on real (with a thin oxide layer) germanium surfaces irradiated by localized (10-100 μm), pulsed (0.1-1 μs) laser light which heats the surface by an estimated ∼20-40 K. It is shown that the thresholds for plastic deformation in the surface region of the semiconductor (due to the resulting local thermal stresses) correspond to threshold changes in the optical charging spectra of slow surface states of the insulator, while no threshold changes are observed for the fast states. The nature of this effect is discussed
