Abstract
Electron mobility limited by deformation potential acoustic phonon scattering is studied for GaAs/Ga0.7Al0.3As and Ga0.47In0.53As/InP quantum wires. Values of mobility are computed for temperatures of 77, 300 and 400 K by taking into account the effects of finite barrier height, energy band non-parabolicity of the constituting materials and the non-zero values of the transverse component of the phonon wavevector. The computed values are found to be significantly lower than those obtained for bulk materials for diameters smaller than 20 nm.
