X-ray diffraction patterns of illuminated As2S3 manifest a structural modification at ∼1 Å-1. Photoinduced birefringence in As2S3 becomes maximal at some temperature, which is higher for illumination with a lower photon energy. The photoinduced birefringence becomes greater in the order of As2Se3, As2S3, and Se, which is the same with the order of the natural birefringence in the corresponding crystals. These observations suggest that the photoinduced anisotropy arises from orientation of quasicrystalline clusters. The model is compared with photoinduced anisotropies observed in other materials.American Physical SocietyJournal Articleapplication/pdfhttp://hdl.handle.net/2115/5731https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/5731/1/PRB54-13.pdf0021-8979Physical Review B5413919091951996-10-01enginfo:doi/10.1103/PhysRevB.54.9190Copyright © 1996 American Institute of Physicspublisher
