Query: Superconducting Order from Disorder in 2H-TaSe$_{2-x}$S$_{x}$
  (0$\leq$x$\leq$2)   We report on the emergence of robust superconducting order in single crystal
alloys of 2H-TaSe$_{2-x}$S$_{x}$ (0$\leq$x$\leq$2) . The critical temperature
of the alloy is surprisingly higher than that of the two end compounds
TaSe$_{2}$ and TaS$_{2}$. The evolution of superconducting critical temperature
T$_{c} (x)$ correlates with the full width at half maximum of the Bragg peaks
and with the linear term of the high temperature resistivity. The conductivity
of the crystals near the middle of the alloy series is higher or similar than
that of either one of the end members 2H-TaSe$_{2}$ and/or 2H-TaS$_{2}$. It is
known that in these materials superconductivity (SC) is in close competition
with charge density wave (CDW) order. We interpret our experimental findings in
a picture where disorder tilts this balance in favor of superconductivity by
destroying the CDW order.
