Pressure and temperature dependence of energy Gap in SiC and Si1-xGex

الملخص EN

The effect of pressure on energy gap for IV-IV compound SiC and Si1-xGex alloy have been investigated and evaluated by using Birch-Murnaghan equation of state (EOS) and Bardeen equation of state.

Ambiguity in the effect of pressure and temperature on Eg of different SiC polytypes (3C, 4H, 6H) have been investigated and attributed.Variation of Eg in Si1-x Gex evaluated and an interpretation, for it, has been suggested.
