LanTraP: A code for calculating thermoelectric transport properties with the Landauer formalism

Abstract

A code for calculating the semi-classical thermoelectric and electronic transport properties is described. It uses the Landauer transport theory, which is equivalent to the Boltzmann theory, by introducing a central quantity-the distribution of modes. Its usage enables the so-called band-counting algorithm that can speed up the calculation and offers the potential to rapidly screen DFT band structures. Good agreements are found when comparing the results obtained using band-counting and established Fourier-based interpolation methods.
