abstract = {With increasing interest in Majorana physics for possible
quantum bit applications, a large interest has been
developed to understand the properties of the interface
between a s-type superconductor and a topological insulator.
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 novel
fabrication process, combining selective area growth and
shadow evaporation which allows the characterization of a
single in-situ fabricated Nb/(Bi0.15Sb0.85)2Te3 nano
interface. 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 peak-like shape of our differential
conductance spectra and the origin of the observed smearing
of conductance features.This dataset contains the DFT and
experimental raw data discussed in the associated
publication.},
