Thecharacterization of interlayer coupling in two-dimensionalvan der Waals heterostructures (vdWHs) is essential to understandtheir quantum behaviors and structural functionalities. Interlayershear and layer-breathing (LB) phonons carry rich information on interlayerinteraction, but they are usually too weak to be detected via standardRaman spectroscopy due to the weak electron-phonon coupling(EPC). Here, we report a universal strategy to enhance LB modes ofvdWHs based on twisted bilayer graphene (tBLG). In both tBLG/hBN andtBLG/MoS2 vdWHs, the resonantly excited electrons in tBLGcan strongly couple to LB phonons extended over the entire layersin the vdWHs, whose resonance condition is tunable by the twist angleof tBLG. In vdWHs containing twisted graphene layers with multipletwisted interfaces, the EPC of LB phonons coming from the collectiveLB vibrations of entire heterostructure layers can be tuned by resonantexcitation of programmable van Hove singularities according to eachtwisted interface. The universality and tunability of enhanced LBphonons by tBLG make it a promising method to investigate EPC andinterlayer interaction in related vdWHs.
