Abstract

The phenomena of unusual light scattering and optical bistability (switching) was observed earlier during exposure of bulk as2s3 and GeS2 in polarized light.1 It was explained as a result of the formation of gigantic dynamic noncrystalline clusters on the base of the soft atomic configuration in the form of three-center bonds.2 The aim of this work was to register by the electroabsorption (EAB) method spectrum of low-energy defects in vitreous GeS22 and to investigate the dynamics of cluster formation since the three-center bonds were extremely sensitive to external fields.
