Fig. 2: Intensity resonances of LB modes in hBN/WSe2/Gr vdWH and its constituents.
From: Probing the interfacial coupling in ternary van der Waals heterostructures
LF Raman spectra of 3L-WSe2, 22L-hBN/3L-WSe2, 3L-WSe2/5LG, and 22L-hBN/3L-WSe2/5LG excited by four Eex. The Eex corresponding to B, C, and D exciton energies of 3L-WSe2 are labeled in brackets. The stars indicate the LB modes and the crosses show TA phonon in WSe230.
