Electronic Structure and Transport Properties of Doped Lead Chalcogenides from First Principles
Published online by Cambridge University Press: 14 August 2016
Abstract
The structural and electronic properties of lead chalcogenides PbX (X=S, Se, and Te) are investigated by first-principles calculations based on the range-separated hybrid functionals and semilocal generalized gradient approximation. It is found that an accurate band structure description requires the hybrid functional with the spin-orbit coupling included. Using this approach, the band structure of lead telluride and doped lead selenide are calculated, and its influences on the transport properties are discussed.
