Charge-polarized interfacial superlattices in marginally twisted hexagonal boron nitride

Charge-polarized interfacial superlattices in marginally twisted hexagonal boron nitride

Here, moiré superlattices generated by twisted insulating crystals of hexagonal boron nitride are shown to have a ferroelectric-like character, attributed to strain-induced polarized dipoles formed by pairs of interfacial boron and nitrogen atoms that create bilayer-thick ferroelectric domains.
