Dative Epitaxy of Commensurate Monocrystalline Covalent van der Waals Moiré Supercrystal

open access: yesAdvanced Materials, 2022
AbstractRealizing van der Waals (vdW) epitaxy in the 1980s represents a breakthrough that circumvents the stringent lattice matching and processing compatibility requirements in conventional covalent heteroepitaxy. However, due to the weak vdW interactions, there is little control over film qualities by the substrate. Typically, discrete domains with a
