Renormalization of hole-hole interaction at decreasing Drude conductivity

Abstract

The diffusion contribution of the hole-hole interaction to the conductivity is analyzed in gated GaAs/In${}_x$Ga${}_{1-x}$As/GaAs heterostructures. We show that the change of the interaction correction to the conductivity with the decreasing Drude conductivity results both from the compensation of the singlet and triplet channels and from the arising prefactor ${\alpha }_i<1$ in the conventional expression for the interaction correction.
