a, SH power generated from 30 monolayers versus isolated monolayers on an identical ECF obtained by the ablation process. b, PL map from a typical MoS2 crystal before removal. The white dashed line displays the bottom of the exposed surface. c, PL map after the removal of the crystal in b using a pulsed laser at 515 nm. d, PL map from the retained crystal.
