Abstract

This article briefly summarizes the Landauer – Datta – Lundstrom electron transport model. Provided a band structure is given, number of conduction modes can be evaluated and, if a model for a mean free pass for backscattering can be established, then the near-equilibrium thermoelectric transport coefficients can be calculated using the final expressions listed below for 1D, 2D, and 3D resistors in ballistic, quasi-ballistic and diffusive linear response regimes when there are differences in both voltage and temperature across the device. The final expressions of thermoelectric transport coefficients through the Fermi – Dirac integrals are collected for 1D, 2D and 3D semiconductors with parabolic band structure and for 2D graphene linear dispersion in ballistic and diffusive regimes with the power law scattering.
