Shaping of the exciton optical reflection spectra of CdSe crystals bombarded by low-energy electrons
Batyrev A. S. , Novikov B. V. , Sel'kin A. V.
The evolution of the spectra of exciton optical reflection of CdSe crystals at T—4.2 К during bombardment of the samples with "slow" (2-keV) electrons has been studied in detail. The mechanism which shapes the surface exciton potential has been identified. It involves a universal electron energy-loss function. © 1995 American Institute of Physics.
