Description
  • Using in situ synchrotron x-ray photoelectron spectroscopy (sXPS), we obtained high resolution As 3d and Se 3d spectra of Se-rich As36Se64 glassy films during illumination with band gap light. We report direct experimental evidence of the chemical origin of the light-induced scalar permanent change in the structure, and more interestingly, the first indication of the chemical origin of the light-induced polarization-dependent (vector) effects. Our data show that the As atom plays a key role in both the permanent scalar effect and the vector effect. The latter is explained by the polarization-dependent interaction of homopolar -As-As- bonds in As4Se4 clusters with the band gap light. The chemical reaction resulting from illumination explains anisotropic properties such as permanent light-induced mass transport
