Recent progress on 2D materials research based on MBE

Abstract

The emergent properties and functionalities of 2D materials and their integrated superstructures are some of the hot topics in materials science. Most studies have been done with nano-thick flakes made by a combination of top-down approaches, exfoliation, pick-up, and dry-transfer techniques. Conversely, the bottom-up approach by molecular-beam epitaxy (MBE) should enable fabrication and integration of a variety of materials including even barely-cleavable, chemically-unstable, and/or thermodynamically-metastable compounds, providing very powerful and important routes for broadening the scope of 2D materials research. In this paper, we will introduce recent progress on 2D materials research based on MBE by mostly focusing on our recent achievements.
