Abstract
Shubnikov—de Haas effect measurements were made in two-dimensional electron gas in liquid phase epitaxially grown Ga0.47In0.53As/InP heterostructures. The quantum scattering time was deduced form the magnetoresistance oscillation amplitudes using Dingle plots. The ratio of classical to quantum scattering times was found to be 1.7 to 5. The experimental results obtained for the ratio of classical to quantum scattering time are discussed in terms of the relevant scattering mechanisms in this system. The role of weak dependence of the scattering cross-section on the scattering angle in Ga0.47In0.53As/InP, i.e. the dominance of alloy scattering is emphasized.
