Proximity-induced charge density waves in a moir'e heterobilayer
This study investigated charge density waves (CDW) in a twisted NbSe2/MoSe2 bilayer using first-principles calculations. CDW formation in MoSe2 is induced by proximity effects from NbSe2, driven primarily by the steric repulsion of Se atoms across the van der Waals gap. The CDW type and amplitude are highly sensitive to the stacking arrangement, suggesting this mechanism could control emergent phases like superconductivity.
