摘要

High-quality large-sized hexagoal WSe₂ crystals can be grown on dielectric substrates using atmospheric chemical vapor deposition in the presence of hydrogen gas. These hexagonal crystals (lateral width >160 um) have a carrier mobility of 100 cm² V^-1 s^-1 and a photoresponsivity of ≈1100 mA W^-1, which is comparable to that of exfoliated flakes.
