Anisotropy of photo-induced deformation in layered ternary thallium compounds

Abstract

Inorganic ternary thallium compounds show a localized and enormous change of the surface relief by light irradiation. In this study, the relationship betweenphoto-induced deformation and crystallographic anisotropy has been investigated for layered ternary thallium compounds. The results show that the anisotropy of the heat conductivity is a key factor for the anisotropic profile of the photo-induced deformation.
