  Here, we have grown single crystals of LaTe2-xSbx (x=0 and 0.4) with
continuously adjustable CDW. High-pressure x-ray diffraction show LaTe2 does
not undergo phase transition and keep robust below 40 GPa. In-situ
high-pressure electrical measurements show LaTe2-xSbx undergo
semiconductor-metal-superconductivity transition at 4.6 and 2.5 GPa,
respectively. With the doping of Sb, the highest Tc increases from 4.6 to 6.5
K. Theoretical calculations reveal that the CDW has been completely suppressed
and the calculated Tc is about 2.97 K at 4.5 GPa, consistent with the measured
value. Then, the pressure-induced superconductivity in LaTe2-xSbx can be
explained in the framework of the BCS theory.
