Based on the ‘bottom-to-top’ approach of the Landauer–Datta–Lundstrom transport model of state-of-the-art nanoelectronics, the thermoelectric Seebeck and Peltier phenomena are considered; the Wiedemann–Franz law and Lorenz numbers as well as the four transport coefficients (specific resistivity, Seebeck and Peltier coefficients, and electronic thermal conductivity) are qualitatively discussed. From the same positions for 3D-resistor within the diffusion regime, thermoelectric cooler and energy power generator are analysed with accounting only electrons as real current carriers as well as within the scope of the artificial but useful ‘hole’ model. Conceptions of operating performances (coefficient of efficiency, power factor, and figure of merit) for thermoelectric devices are introduced and defined, and dependences of transport coefficients on the properties of termics are discussed.
