PiezoelectricTensor¶

class py4vasp.raw.PiezoelectricTensor(electron: VaspData, ion: VaspData)¶

Bases: object

The piezoelectric tensor calculated in a linear response calculation.

The piezoelectric tensor describes how an electric field induces a stress on the crystal. Equivalently, straining the system can induce a polarization. VASP splits the piezoelectric tensor into an electronic and an ionic contribution.
