From: General synthesis of two-dimensional van der Waals heterostructure arrays
a, Typical optical microscopy image of a VSe2/WS2 vdWH array. b, Raman spectra of the bare WS2 and the overlapping VSe2/WS2 vertical heterostructure. c, d, Raman intensity mapping image of VSe2/WSe2 vdWH arrays at resonant peaks of 353 cm−1 (WS2; c) and 206 cm−1 (VSe2; d). e, Photoluminescence spectra of the bare WS2 and the overlapping VSe2/WS2 vertical heterostructure. f, Photoluminescence intensity mapping image at 658 nm (WS2 emission).
