Relaxation Processes in a Quantum Wire with Parabolic Confinement
Keywords:mobility of a two-dimensional electron gas, quantum wire, elastic scattering by ionized impurities, scattering by acoustic phonons, parabolic confinement potential
Analytical expressions are found for the mobility of a degenerate electron gas in a quantum wire for three scattering mechanisms: on ionized impurities and on piezoacoustic and deformation acoustic phonons. The expressions allow one to analyze the concentration, temperature, and dimensional dependences of the electron mobility.
