Hole-Hole Interaction Effect in the Conductance of the Two-Dimensional Hole Gas in the Ballistic Regime
Y. Y. Proskuryakov, A. K. Savchenko, S. S. Safonov +3
On a high mobility two-dimensional hole gas (2DHG) in a GaAs/GaAlAs heterostructure we study the interaction correction to the Drude conductivity in the ballistic regime, $k_BTτ/\h…
Modulation origin of 1/f noise in two-dimensional hopping
V. Pokrovskii, A. K. Savchenko, W. R. Tribe +1
We show that 1/f noise in a two-dimensional electron gas with hopping conduction can be explained by the modulation of conducting paths by fluctuating occupancy of non-conducting s…
Fermi-liquid behaviour of the low-density 2D hole gas in GaAs/AlGaAs heterostructure at large values of r_s
Y. Y. Proskuryakov, A. K. Savchenko, S. S. Safonov +3
We examine the validity of the Fermi-liquid description of the dilute 2D hole gas in the crossover from 'metallic'-to-'insulating' behaviour of R(T).It has been established that, a…
