On the problem of electron-induced anisotropy effect in As2S3-based glasses

Effect of electron-induced anisotropy was observed in glassy As2S3-based sa mples irradiated by accelerated electrons (E = 2.8 MeV) in the perpendicula r plane to the probe light. Spectral and compositional dependences of this effect and its time stability at room temperature were discussed. It was su pposed that the microstructural mechanism of the anisotropy effect was conn ected with electron-induced formation of new oriented (relatively to the el ectron flow) defects in the form of broken chemical bonds, (C) 2000 Elsevie r Science B.V.
