Radiation-induced defects influence on the electrical, photoelectrical and optical properties of chalcogenide glasses

Structural and optical changes in As2S3 thin films induced by light ion irradiation

“…Further the energy is transferred to the lattice via electron-phonon coupling. It is supported by the fact that similar optical and structural changes have been observed in chalcogenide glasses under the influence of electron, γ-, and X-ray irradiation [5,6,13,14,16]. The above mentioned indicates that the mechanism of producing such structural changes could not be very specific to the excitation of the structure by light, i.e.…”

“…Although the mechanisms of interaction of the light and ionizing irradiation with solids are far not the same, some common aspects of their effects on chalcogenide glasses may be established and the mechanism of induced structural transformations in amorphous chalcogenides may be considered from more general viewpoint. The significant phenomenological similarity between the light-and electron-induced effects has already been noted by Sarsembinov et al [16]. In addition to the fundamental interest such effects including the depth profiled structural transformations induced by light ions may be used for creating optoelectronic elements.…”

Effects of γ-irradiation on the optical properties of a-(Sb0.1Ge0.3Se0.6) and Ag5(Sb0.1Ge0.3Se0.6)95 thin film material

“…Photodiffusion phenomena was discussed from several different viewpoints and it seems that some of these effects should not be treated as a result of radiation damage of the materials in traditional meaning, but most probably there can be found some similarity with ion beam modification of polymers [9]. ChSG are often considered as inorganic polymers and their structure can be changed by laser illumination or other irradiation [10][11][12][13].…”

Coordination Defects in Vitreous As2S3Induced by γ -irradiation

“…Amorphous chalcogenide semiconductors (AChS), studied by Kolomiets and Goryunova more than forty years ago, are unique solid state materials showing changes of physical properties stimulated by external factors as absorbed light (photoinduced effects [I, 2]), γ-quanta of 60 Co radioisotope or accelerated electrons with average energy E > 1 MeV (radiation-induced effects [3][4][5][6][7][8]). Reversible changes in optical properties of AChS are observed in multiple cycles of irradiation and thermal annealing at temperatures near the glass transition.…”

“…In spite of a large number of scientific publications on photo and radiation--induced processes in AChS [1][2][3][4][5][6][7][8], the detailed analysis of bond switching leading to the CD formation, supported by direct experimental data, have not been carried (577) out yet. This situation is caused b y the difficulties in local atomic structure investigation in disordered solids (AChS, in particular) using "traditional» amorphographical techniques.…”
