Distinctive features of the behavior of the conductivity indicate the presence of multiple Andreev reflection at scattering centers in the normal region near the superconductor-semiconductor boundary. %K 2DEG %K AlGaAs/GaAs heterostructures %R 10.1134/1.1187726 %U http://link.springer.com/10.1134/1.1187726 %U https://doi.org/10.1134/1.1187726 %P 551-554
