The variation of the equilibrium of chemical reactions in the process of (Bi/sub 2/Te/sub 3/)(Sb/sub 2/Te/sub 3/)(Sb/sub 2/Se/sub 3/) zone-melted material production

Abstract

Methods of thermodynamic computation and differential thermal analysis were used for research into the effect of the variation of the chemical equilibrium in the synthesis of (Bi/sub 2/Te/sub 3/)/sub x/(Sb/sub 2/Te/sub 3/)/sub y/(Sb/sub 2/Se/sub 3/)/sub z/ (x+y+z=100%) in an ampoule on the characteristics of crystals grown by the vertical zone-melting technique.
