Ferroelectric switching of interfacial dipoles in $\alpha$-RuCl${}_3$/graphene heterostructure

Soyun Kim, Jo Hyun Yun, Junsik Choe +8

We demonstrate electrically switchable, non-volatile dipoles in graphene/thin hBN/$\alpha$-RuCl${}_3$ heterostructures, stabilized purely by interfacial charge transfer across an atomical…
