Enhanced van der Waals (vdW) epitaxy of semiconductors on a layered vdW substrate is identified as the formation of dative bonds. For example, despite that NbSe2 is a vdW layeredmaterial, first-principles calculations reveal that the bond strength at a CdTe-NbSe2 interface is five times as large as that of vdW interactions at a CdTe-graphene interface. Finally, the unconventional chemistry here is enabled by an effective net electron transfer from Cd dangling-bond states at a CdTe surface to metallic nonbonding NbSe2 states, which is a necessary condition to activate the Cd for enhanced binding with Se.
