Landauer Transport Properties (LanTraP) is an online tool, aimed at assisting research and education, that compute the electronic and phonon thermoelectric properties of materials. LanTraP is based on the Landauer transport formalism, which readily and naturally spans from ballistic to quasi-ballistic transport regimes. The tool allows for a .txt file containing band structure information to be uploaded, and combined with information on the mean-free-path for backscattering, will calculate (i) the distribution of modes and (ii) the thermoelectric properties.

LanTraP is similar to the BoltzTraP code, but utilizes the Landauer formalism instead of the Boltzmann transport formalism. With LanTraP the physics of scattering is determined via the mean-free-path for backscattering, while with BoltzTraP scattering is set through the scattering time. In the diffusive transport regime, where the material length is many times longer than the mean-free-path, LanTraP can be shown equivalent to BoltzTraP. For more information about thermoelectric transport theory and the Landauer formalism, see Near-Equilibrium Transport: Fundamentals and Applications.
