Controlling the Epitaxial Growth of BiTe, BiTe, and BiTe Pure Phases by Physical Vapor Transport.

BiTe is a well-studied material because of its thermoelectric properties and, recently, has also been studied as a topological insulator. However, it is only one of several compounds in the Bi-Te system. This work presents a study of the physical vapor transport growth of Bi-Te material focused on determining the growth conditions required to selectively obtain a desired phase of the Bi-Te system, i.
