Phonon Drag Thermopower in Quantum Wire with Parabolic Confinement Potential

Year: 2017

Type: article

Abstract: The quantitative theory of phonon drag thermopower for the one-dimensional electron gas in a quantum wire with a parabolic confinement potential is developed.The temperature gradient is directed along the axis of a quantum wire.As assumed, the Fermi level is located between the zero and first levels of a size quantization.Using the Boltzmann kinetic equation, the phonon and electronic parts of a thermoelectric power are calculated.For comparison, numerical calculations of the temperature and concentration dependences of the phonon and diffusion parts of a thermoelectric power are carried out.As shown, the phonon drag makes a main contribution in thermopower within the temperature interval 2-20 K.
