AMSET: ab initio scattering and transport


amset properties

AMSET is an efficient package for calculating electron lifetimes and transport properties in solid-state materials from first principles. A primary aim of AMSET is to be amenable to high-throughput computational screening. Features of AMSET include:

  • Inputs obtainable from first-principles calculations. The primary input for AMSET is an uniform band structure calculation.
  • Scattering rates calculated in the Born approximation using common materials properties such as phonon frequencies and dielectric constants.
  • Transport properties calculated through the Boltzmann transport equation.
  • Efficient implementation that can run on a personal laptop.

Supported ab initio codes

Currently, AMSET only supports VASP calculations, however, additional periodic DFT codes will be added in the future.

Scattering Mechanisms

The scattering mechanisms currently implemented in AMSET are:

  • Acoustic deformation potential scattering
  • Ionized impurity scattering
  • Polar optical phonon scattering
  • Piezoelectric scattering

More information on the formalism for each scattering mechanism is available in the scattering section of the documentation.
