a LF Raman spectra of 7LG, 7LG/23L-hBN, and 7LG/23L-hBN/2L-MoTe2. b Raman spectra of 2L-MoTe2, 23L-hBN/2L-MoTe2, and 7LG/23L-hBN/2L-MoTe2. c The calculated intensities of the LB modes in 23L-hBN/2L-MoTe2 and 7LG/23L-hBN/2L-MoTe2 based on the phonon wave function projection method19. The dashed lines and stars indicate Pos(S) and Pos(LB), respectively.
