title = "Multiple Andreev reflection in hybrid AlGaAs/GaAs structures with superconducting NbN contacts",
abstract = "The conductivity of hybrid microstructures with superconducting contacts made of niobium nitride to a semiconductor with a two-dimensional electron gas in a AlGaAs/GaAs heterostructure has been investigated. 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.",

note = "Funding Information: In summary, we have investigated a new S-2DEG-S system based on a two-dimensional electron gas in an AlGaAs/ GaAs heterostructure with contacts made of superconducting NbN. The distinctive features of the conductivity we observed point to the important role of multiple Andreev reflection at the scattering centers12 in determining the transparency of the superconductor-semiconductor barrier at temperatures below the critical temperature in the superconducting {\textquoteleft}{\textquoteleft}banks.{\textquoteright}{\textquoteright} This work was carried out with the support of grants No. 96-02-18614 from the Russian Fund for Fundamental Research, NATO HTECH.LG-960606, the program {\textquoteleft}{\textquoteleft}Physics of Solid-State Nanostructures{\textquoteright}{\textquoteright} (No. 1-069/4), and {\textquoteleft}{\textquoteleft}Current Scientific Schools{\textquoteright}{\textquoteright} (No. 96-15-96426).",
