## Phonon-Drag Thermopower in a Quantum Wire with Parabolic Confinement Potential for Electrons

**Background and Objectives:** A quantitative theory of the phonondrag thermopower for one-dimensional degenerate electron gas in a quantum wire with parabolic confinement potential is presented. The temperature gradient is directed along the axis of the quantum wire. Due to the confinement, the energy spectrum and the wave function of the electron change substantially. It is assumed that the Fermi level is located between the zeroth and the first of the size quantization.
