Extended Data Fig. 5: Diffusion measurements in multiple locations on the ML MoSe2/t-hBN.
From: Electrostatic moiré potential from twisted hexagonal boron nitride layers
a-c, Normalized pump-probe images from the second position on the ML MoSe2/t-hBN at delay times 0 ps (a), 2.5 ps (b), and 5 ps (c). The scale bar is 1 μm. d, Line profiles taken along the white dashed lines in (a-c). The solid lines are Gaussian fittings. e-h, Corresponding images and line profiles from the third position on the ML MoSe2/t-hBN. The solid lines are Gaussian fittings. The grey dashed lines represent the laser profile. The exciton density is the same as the main text of ~ 7 × 1011 cm−2.
