Abstract

First principles calculations were performed to explain the deformation feature and band gap variation behavior of PbTe under isotropic and uniaxial strain along [100], [110] and [111] directions. Calculations showed that the band gap variation regularity is quite different between the first and the last two cases due to the different lattice deformation modes. The introduction of shearing strain may significantly reduce the band gap of PbTe, and therefore the band structure of PbTe can be modulated by introducing proper strain.
