光誘起相転移・光誘起現象の観点から迫る分子性固体 The Molecular Solid from a Viewpoint of Photo-Induced Phase Transition and Related Phenomena
In this paper, we introduce the electronic states and electronic properties of molecular solid especially charge transfer salts and radical salts in the aspect of photo-induced phase transition and related phenomena. The characteristic features of molecular solid, which deeply related to photo-induced phase transition, are as following:(1) low-dimensional electronic states originated from anisotropic interaction,(2) strong electronic correlation induced by low carrier concentration,(3) lattice softness which causes competition of electronic phases with pressure and thermal contraction,(4) internal-freedom, namely, molecular motions. We propose strategies for exploring possible candidates for forthcoming materials with photo-induced phase transition.
