Abstract:
We experimentally investigate transport properties of a single planar junction between the
niobium superconductor and the edge of a two-dimensional electron system in a narrow
In$_{0.75}$Ga$_{0.25}$As quantum well with strong Rashba-type spin-orbit coupling. We
experimentally demonstrate suppression of Andreev reflection at low biases at ultra low
temperatures. From the analysis of temperature and magnetic field behavior, we interpret
the observed suppression as a result of a spin-orbit coupling. There is also an
experimental sign of the topological superconductivity realization in the present structure.
