Query: Visualizing superconductivity in an inversion-symmetry-broken doped Weyl
  semimetal   The Weyl semimetal MoTe$_2$ offers a rare opportunity to study the interplay
between Weyl physics and superconductivity. Recent studies have found that Se
substitution can boost the superconductivity up to 1.5K, but suppress the Td
structure phase that is essential for the emergence of Weyl state. A
microscopic understanding of possible coexistence of enhanced superconductivity
and the Td phase has not been established so far. Here, we use scanning
tunneling microscopy (STM) to study a optimally doped new superconductor
MoTe$_{1.85}$Se$_{0.15}$ with bulk Tc ~ 1.5K. By means of quasiparticle
interference imaging, we identify the existence of low temperature Td phase
with broken inversion symmetry where superconductivity globally coexists.
Consistently, we find that the superconducting coherence length, extracted from
both the upper critical field and the decay of density of states near a vortex,
is much larger than the characteristic length scale of existing dopant derived
chemical disorder. Our findings of robust superconductivity arising from a Weyl
semimetal normal phase in MoTe$_{1.85}$Se$_{0.15}$, makes it a promising
candidate for realizing topological superconductivity.
