Abstract

The absorption edge of monocrystaline CuInP2S6 was studied in the 77-303K temperature range, including the range of ferroelectric phase transition. The absorption mechanism resulting in direct optical transition in ferroelectric phase and in exponential form of absorption edge in paraelectric phase was analyzed. The evolution of chemical interaction CuInP2S6 crystals was studied.
