  Recently, we presented a paper about the tip-induced superconducting phase on
TaAs single crystal (arXiv:1607.00513). A conductance plateau with double
conductance peaks at finite bias, sharp double dips and a zero bias conductance
peak were observed in the point contact spectra (PCS). These three features in
one PCS suggest the possibility of p-wave like superconductivity and Majorana
zero modes in the surface. Soon after our paper posted on arXiv, Gayen el al.
(arXiv:1607.01405) questioned the underlying mechanism of our observations
based on their experimental measurements in conventional superconductors(Pb and
Nb) and conclusively indicated that the superconductivity observed in our TaAs
crystal is conventional. We disagree with their quick conclusion without any
specific study on the TaAs materials. We will explain in the following that for
the clean (Z=0) point contact (PC) in ballistic limit, the superconducting
transition feature in temperature dependence of PC resistance is expected. And
the critical current effect claimed by Gayen el al. cannot explain the observed
PCS in our paper.
