HIGHLIGHTS
- who: Ruirui Niu from the (UNIVERSITY) have published the article: Giant ferroelectric polarization in a bilayer graphene heterostructure, in the Journal: (JOURNAL) of 12/07/2022
- what: By studying a Bernal bilayer graphene moiru00e9 superlattice encapsulated by 30u00b0-twisted boron nitride flakes, the authors report an unprecedented ferroelectric polarization with the areal charge density up to 1013 cm-2, which is far beyond the capacity of a moiru00e9 band. The authors take advantages of clear moiru00e9 peaks and Landau levels (LL) to quantitatively explore ferroelectricity and anomalous screening.
