“…Due to the crystallization, it is difficult to evaluate precisely the change of the refractive index and/or the absorption coefficient. In addition, the variation of thickness is strongly suppressed by the presence of hard barriers in NM Ls, as it was shown for As 20 Se 80 /AS NMLs [20].…”

International audienceAmorphous selenium (a-Se) is the simplest model material for investigation of the well-known photoinduced structural and optical transformations in amorphous chalcogenides. Since a lot of parameters and characteristics of materials essentially change at nanoscale, we applied nanostructuring to a -Se in nanomultilayers, obtained by pulsed laser deposition. The enhancement of photo- and thermally-induced crystallization was observed in a-Se/aluminosilicate nanomultilayers due to the initially heterogeneous state of Se in such samples, in comparison with single a -Se layers

“…In order to counteract mentioned problem of deposition rate reproducibility or to have the opportunity of an efficient wavelength tuning or, conversely, to stabilize the photoinduced effects in chalcogenide films, we test several pairs of materials from pure chalcogenide layers to chalcogenide/oxide layers. In the case of the use of alumino-silicates, the photosensitivity and photoexpansion of the multilayer structure can be expected to be reduced [24]. The combination of the oxide films with the chalcogenides can also play an advantageous role in the mechanical properties as well as their chemical durability against aging in natural atmosphere [23,25].…”
