Abstract:

Temperature and magnetic-field dependences of the conductivity in heavily doped, strongly disordered two-dimensional quantum well structures GaAs/InxGa1-xAs/GaAs are investigated within wide conductivity and temperature ranges. The role of the interference in electron transport is studied in the regimes where the phase breaking length L-phi crosses over the localization length xi similar to l exp(pi k(F)l/2) with decreasing temperature, where k(F) and l are the Fermi quasimomentum and mean free path, respectively. It is shown that all the experimental data can be understood within a simple model of the conductivity over delocalized states. This model differs from the conventional model of weak localization developed for k(F)l > 1 and L-phi
