THE AV–BVI–I TERNARY SYSTEMS: A BRIEF REVIEW ON THE PHASE EQUILIBRIA REVIEW

Abstract

This paper presents a brief review on the ternary phase equilibria in the ternary AV–BVI–I systems (AV = Sb, Bi; BVI = S, Se, Te). These systems includes the series of ternary compounds those are very attractive source materials for photo-, thermos- and ferroelectric energy transformation along the recently discovered semiconductors that exhibit Rashba-type spin splitting in their surface states. In the Rashba semiconductors, a unique toroidal 3D Fermi surface appears on the crystal surface, which leads to unusual properties that make it possible to realize unique electronic devices based on these compounds. The thorough knowledge on the ternary phase diagram of these systems shed light on the chemical and structural design of new multifunctional materials with tunable properties. This knowledge is very important when focusing on the chemistry of such multifunctional materials based on complex element systems.
