Abstract:

The theory of weak localization is presented for quasi-2D systems where several sub- bands of size quantization are occupied. The weak-localization correction to conductivity is shown to depend strongly on the level concentration ratio and intersubband scattering intensity. Specifically at the comparable level occupations and equal relaxation times the conductivity correction of the m-subband system decreases in m times when transiting from the isolated levels to the high-intensive intersubband scattering case.
