The Shubnikov-de Haas oscillations have been analysed to extract the quantum scattering lifetime, τq, and this is compared with the classical transport lifetime, τt, derived from the low-field mobility. The relationship between these parameters has been observed to depend systematically on the low-field mobility of the samples studied, and indicates that higher-mobility samples suffer less scattering from centres close to the two-dimensional conducting channel.Show less >
