Abstract:

The electron-electron interaction quantum correction to the conductivity of the gated single quantum well InP/In0.53Ga0.47As heterostructures is investigated experimentally. The analysis of the temperature and magnetic field dependences of the conductivity tensor allows us to obtain the diffusion part of the interaction correction for different values of spin-relaxation rate, 1/tau(s). The surprising result is that the spin-relaxation processes do not suppress the interaction correction in the triplet channel and thus do not enhance the correction in magnitude contrary to theoretical expectations even in the case of relatively fast spin relaxation, 1/T tau(s) similar or equal to (20 - 25) >> 1.
