OpticalDeformationPotentialSelfEnergy

class OpticalDeformationPotentialSelfEnergy(coupling=None, phonon_energy=None)

A class which represent a deformation potential model for acoustic phonon modes.

Parameters:

• coupling (PhysicalQuantity of type energy) – The electron-phonon coupling strength of the optical modes. The coupling strength can be given as a single value, or a 1D array specifying the value for each atom (in units of energy).
  Default: 0 * eV

• phonon_energy (PhysicalQuantity of type energy) – The energy of the optical modes, assumed constant.
  Default: 0.063 * eV

coupling()

Return type:

PhysicalQuantity with unit eV**2

phononEnergy()

Returns:

The optical phonon energy, assumed constant.

Return type:

PhysicalQuantity of type energy

uniqueString()

Return a unique string representing the state of the object.
