“…The diffusional intermixing affects several parameters of the multilayer structure, such as optical absorption edge, layer thickness, photoluminescence intensity, electrical conductivity, and photoconductivity. 2,3,6 The experiments indicate that the light-and thermostimulated diffusion effects are rather similar. The changes in these properties are explained based on the formation of ternary solid solution due to interdiffusion.…”

We have studied the kinetics of photoinduced effects in nanolayered Se/ As 2 S 3 film by in situ optical absorption measurements, which reveal that photodarkening in these films is followed by photoinduced diffusion. An increase in disorder during photodarkening and its subsequent decrease during photoinduced diffusion were also observed. The observation of photodarkening of Se at room temperature when confined between As 2 S 3 layers suggests that the glass transition temperature of Se shifts to higher energy. The analysis shows that the atoms which take part in photodarkening play a vital role in photoinduced diffusion. The x-ray photoelectron spectroscopy measurements show the atomic movements during photoinduced diffusion. It also shows that some of the As-S bonds are converted into As-Se bonds. Since it is energetically difficult to break an As-S bond to form an As-Se bond, we assume that the new bond formations are taking place by the bond rearrangement mechanism.

“…The stimulated interdiffusion in MLS belongs to the type (iii) PST and also essentially depends on the modulation period [16]. Since interdiffusion is efficient in the systems, where solid solutions can be formed (for example Se-Te, Se-As 2 S 3 , As x Se 1Àx , Se x Te 1Àx , etc.…”

In this report the study of direct holographic recording of the surface relief gratings on amorphous chalcogenide thin (0.5-10 µm) films is presented in view of the light polarization state. Recording was performed on As2S3 by 532 nm wavelength laser light. Because of direct surface relief formation, its efficiency may also depend on the softening temperature of the film material, which was studied using additional incoherent laser light for extra illumination during holographic recording. The results have shown that the efficiency of surface relief formation is many times higher in the case of extra illumination by additional incoherent light during recording. The mechanism of the direct recording of surface relief on amorphous chalcogenide films based on the photoinduced plasticity is discussed.
