Temperature-dependent disorder and magnetic field driven disorder: experimental observations for doped GaAs/AlGaAs quantum well structures
N. V. Agrinskaya, V. A. Berezovets, V. I. Kozub
We report experimental studies of conductance and magnetoconductance of GaAs/AlGaAs quantum well structures where both wells and barriers are doped by acceptor impurity Be. Tempera…
Suppression of the virtual Anderson transition in a narrow impurity band of doped quantum well structures
N. V. Agrinskaya, V. I. Kozub, D. S. Poloskin
Earlier we reported an observation at low temperatures of activation conductivity with small activation energies in strongly doped uncompensated layers of p-GaAs/AlGaAs quantum wel…
Magnetoresistance in semiconductor structures with hopping conductivity: effects of random potential and generalization for the case of acceptor states
N. V. Agrinskaya, V. I. Kozub, A. V. Shumilin +1
We reconsider the theory of magnetoresistance in hopping semiconductors. First, we have shown that the random potential of the background impurities affects significantly preexpone…
