Wafer-Scale Single-Crystalline AB-Stacked Bilayer Graphene

Abstract

Single-crystalline artificial AB-stacked bilayer graphene is formed by aligned transfer of two single-crystalline monolayers on a wafer-scale. The obtained bilayer has a well-defined interface and is electronically equivalent to exfoliated or direct-grown AB-stacked bilayers.

Keywords: AB-stacked bilayers; graphene growth; quantum Hall effect; single crystalline; wafer-scale.
