Query: Signature of proximity induced triplet superconductivity in junctions
  made of the doped topological insulator $\rm Bi_2Se_3$ and the s-wave
  superconductor NbN   Thin film junctions and bilayers of the doped topological insulator $\rm
Bi_2Se_3$ and the s-wave superconductor NbN were found to exhibit conductance
spectra with prominent zero bias and coherence peaks. Various tunneling models
with different pair potentials have failed to fit our data, except for the
triplet $p_x+ip_y$ pair potential, which breaks time reversal symmetry, but
yielded reasonably good fits. This provides evidence for proximity induced
triplet superconductivity in the $\rm Bi_2Se_3$ layer near the interface with
the NbN film.
