High Pressure Study of Structural and Electronic Properties of PbSe

Figure 1

The calculated energy versus volume for B1, B27, and B2 phases of PbSe: using the PBE (a) and VBH (b) correlation functional. The scattered points show calculated energies and the solid lines show the fitted curves according to Birch-Murnaghan equation of state (EOS).
