# Effect of hydrostatic pressure and uniaxial strain on the electronic structure of Pb 1 − x Sn x Te

@article{Geilhufe2015EffectOH, title={Effect of hydrostatic pressure and uniaxial strain on the electronic structure of Pb 1 − x Sn x Te}, author={Matthias Geilhufe and Sanjeev K.

The electronic structure of ${\mathrm{Pb}}_{1\ensuremath{-}x}{\mathrm{Sn}}_{x}\mathrm{Te}$ is studied by using the relativistic Korringa-Kohn-Rostoker Green function method in the framework of density functional theory. For all concentrations $x, {\mathrm{Pb}}_{1\ensuremath{-}x}{\mathrm{Sn}}_{x}\mathrm{Te}$ is a direct semiconductor with a narrow band gap. In contrast to pure lead telluride, tin telluride shows an inverted band characteristic close to the Fermi energy. It will be shown that…
