Abstract
Lattice parameters and distribution coefficients for the Bi2Te3‐Bi2Se3 pseudobinary alloy system have been determined for several compositions across the phase diagram. The c lattice constant (based on a hexagonal lattice) shows deviation from Vegard's law between 33% Bi2Se3 and pure Bi2Se3 with maximum deviation at 67% Bi2Se3. Thermal energy gap as a function of composition shows a maximum near 33% Bi2Se3 and a minimum near 67% Bi2Se3. It is postulated that at least two sets of energy band minima are present in this alloy system.This publication has 10 references indexed in Scilit:
