Static and dynamic order of cooperative multi-electron transfer

摘要: We report on high correlation and ordering of multi-electron transfer at neutral-ionic transformation in quasi–one-dimensional prototype crystal tetrathiafulvalene-chloranil (TTF-CA). present experimental evidences that the lattice-relaxed charge-transfer strings, which are nano-scale objects, occurs under static thermal equilibrium condition non-equilibrium one achieved by femto-second laser irradiation. suggest is a profound example self-organized, cooperative electron with tendency for phase separation driven energetics inter-chain interaction ferroelectric ordering.
