Acoustic Deformation Potentials of $n$-Type PbTe from First Principles

Aoife R. Murphy, Felipe Murphy-Armando, Stephen Fahy +1

We calculate the uniaxial and dilatation acoustic deformation potentials, ${\Xi }_u^{\text{L}}$ and ${\Xi }_d^{\text{L}}$, of the conduction band L valleys of PbTe from first principles,…
