Up to this point the interface analysis was mainly focused on in situ prepared Josephson junctions, which consist of two coupled single interfaces or to ex situ fabricated single interface devices. In our work we utilize a fabrication process, combining selective area growth and shadow evaporation which allows the characterization of a single in situ fabricated Nb/(Bi0.15Sb0.85)2Te3 nanointerface. The resulting high interface transparency is apparent by a zero bias conductance increase by a factor of 1.7. Furthermore, we present a comprehensive differential conductance analysis of our single in situ interface for various magnetic fields, temperatures, and gate voltages. Additionally, density functional theory calculations of the superconductor/topological insulator interface are performed in order to explain the peaklike shape of our differential conductance spectra and the origin of the observed smearing of conductance features.}, cin = {PGI-9 / PGI-6 / PGI-1}, ddc = {530}, cid = {I:(DE-Juel1)PGI-9-20110106 / I:(DE-Juel1)PGI-6-20110106 / I:(DE-Juel1)PGI-1-20110106}, pnm = {5211 - Topological Matter (POF4-521) / DFG project 390534769 - EXC 2004: Materie und Licht für Quanteninformation (ML4Q) (390534769)}, pid = {G:(DE-HGF)POF4-5211 / G:(GEPRIS)390534769}, typ = {PUB:(DE-HGF)16}, UT = {WOS:001195873700004}, doi = {10.1103/PhysRevMaterials.8.034205}, url = {https://juser.fz-juelich.de/record/1024257}, }
