Query: Suppression of surface p-wave superconductivity in disordered
  topological insulators   The paper proposes a self-consistent Green function description of the
induced surface superconductivity in a disordered three-dimensional topological
insulator (TI) coupled to an s-wave superconductor. We recover earlier results
regarding the induced spin-triplet p-wave pairing, showing that a mixture of p-
and s-wave pair correlations appears as a result of broken spin-rotation
symmetry on the helical surface of the TI. Unlike the s-wave pairing, the
p-wave component is found to be suppressed in dirty TIs in which the elastic
mean-free path is much smaller than the superconducting coherence length. The
suppression is due to the generic nonlocality of the spin-triplet correlations,
which makes them strongly dependent on the mean-free path in a disordered
system. In dirty TIs the induced superconductivity is predicted to be
predominantly s-wave like. In cleaner TIs, however, the p-wave component may
reach a magnitude comparable with (but not larger than) the s-wave pairing.
