    Notes: Prominent surface deformations appear in Ag–As–S chalcogenide glasses when exposed to focused laser beams. Deformation behaviors change with the beam diameter, the photon energy, the temperature at which illumination is provided, and the sample composition. In thin AgAsS2 films exposed at room temperature to a 2.0 eV light spot with a diameter of 2 μm, an isotropic convex structure with a height of ∼0.1 μm appears. The expanded region accompanies an Ag-content enhancement by ∼3 at. %, which suggests that the deformation is caused by photoinduced accumulation of Ag+ ions. © 2001 American Institute of Physics.

    Photoinduced surface deformations in ion-conducting Ag–As–S glasses. II. Anisotropic deformation produced by large light spots (2001)

    Notes: Anisotropic surface deformations appear in AgAsS2 chalcogenide films when exposed to linearly polarized 2.0 eV light spots with diameters of 5–200 μm. The anisotropic shape reflects the polarization direction. The shape also changes with the direction of light incidence. Illumination on the free surface of the films gives a craterlike deformation, and illumination through a substrate gives an anticrater deformation. In bulk samples, under any exposure conditions, an isotropic convex structure appears. The formation mechanisms of these patterns are discussed taking into account the photoinduced migration of Ag+ ions. © 2001 American Institute of Physics.
