N2 - We experimentally investigate Andreev transport through a single junction between an s-wave indium superconductor and a thick film of a three-dimensional Bi2Te3 topological insulator. We study Bi2Te3 samples with different bulk and surface characteristics, where the presence of a topological surface state is confirmed by direct ARPES measurements. All the junctions demonstrate Andreev transport within the superconducting gap. For junctions with transparent In-Bi2Te3 interfaces we find a number of nearly periodic conductance oscillations, which are accompanied by zero-bias conductance anomaly. Both effects disappear above the superconducting transition or for resistive junctions. We propose a consistent interpretation of both effects as originating from proximity-induced superconducting correlations within the Bi2Te3 topological surface state.
