Fig. 3

a Schematic diagram of LCM for hBN/TMD, TMD/Gr, and hBN/TMD/Gr vdWHs. b LF Raman spectra of 13L-hBN/3L-MoTe2/8LG, 19L-hBN/3L-MoS2/4LG, and their corresponding binary hBN/TMD, TMD/Gr vdWHs and individual TMD flakes. c Calculated (hollow circles) and experimental (filled symbols) Pos(LB) in mL-hBN/nL-TMD/kLG vdWHs (TMD = WSe2, MoTe2, and MoSe2). Indexes (m, n, k) represent the number of layers of the constituents in each vdWH.
