Band Alignment and Minigaps in Monolayer MoS2-Graphene van der Waals Heterostructures.
Two-dimensional layered MoS2 shows great potential for nanoelectronic and optoelectronic devices due to its high photosensitivity, which is the result of its indirect to direct band gap transition… Expand
Tunable quasiparticle band gap in few-layer GaSe/graphene van der Waals heterostructures
Two-dimensional (2D) materials have recently been the focus of extensive research. By following a similar trend as graphene, other 2D materials including transition metal dichalcogenides (MX2) and… Expand
Interface dipole and band bending in the hybrid p − n heterojunction Mo S 2 / GaN ( 0001 )
Hybrid heterostructures based on bulk GaN and two-dimensional (2D) materials offer novel paths toward nanoelectronic devices with engineered features. Here, we study the electronic properties of a… Expand
Wigner and Kondo physics in quantum point contacts revealed by scanning gate microscopy.
Quantum point contacts exhibit mysterious conductance anomalies in addition to well-known conductance plateaus at multiples of 2e(2)/h. These 0.7 and zero-bias anomalies have been intensively… Expand
Epitaxial graphene on 4H-SiC(0001) grown under nitrogen flux: evidence of low nitrogen doping and high charge transfer.
Nitrogen doping of graphene is of great interest for both fundamental research to explore the effect of dopants on a 2D electrical conductor and applications such as lithium storage, composites, and… Expand
