abstract = {Interfacing a topological insulator (TI) with an s-wave
superconductor (SC) is a promising material platform that
offers the possibility to realize a topological
superconductor through which Majorana-based topologically
protected qubits can be engineered. In our computational
study of the prototypical SC/TI interface between Nb and
Bi₂Te₃, we identify the benefits and possible
bottlenecks of this potential Majorana material platform.
Bringing Nb in contact with the TI film induces charge
doping from the SC to the TI, which shifts the Fermi level
into the TI conduction band. For thick TI films, this
results in band bending leading to the population of trivial
TI quantum-well states at the interface. In the
superconducting state, we uncover that the topological
surface state experiences a sizable superconducting
gap-opening at the SC/TI interface, which is furthermore
robust against fluctuations of the Fermi energy. We also
show that the trivial interface state is only marginally
proximitized, potentially obstructing the realization of
Majorana-based qubits in this material platform.This dataset
contains the data for the DFT-based calculations for
interfaces between the s-wave superconductor Nb and the
topological insulator Bi₂Te₃ which is discussed in the
publication referenced below.},
