First Principles Study of Electronic Structure and Transport in Graphene Grain Boundaries
Aleksander Bach Lorentzen, Fei Gao, Peter Bøggild +2
Grain boundaries play a major role for electron transport in graphene sheets grown by chemical vapor deposition. Here we investigate the electronic structure and transport properti…
Terahertz s-SNOM reveals nonlocal nanoscale conductivity of graphene
Henrik B. Lassen, William V. Carstensen, Leonid Iliushyn +4
As photonic and electronic technologies approach nanometre length scales and terahertz operating speeds, electrical conductivity can no longer be treated as a purely local material…
A High-Performance Quasi-1D MoS Nanoribbon Photodetector
Ganesh Ghimire, Rajesh Kumar Ulaganathan, Agnes Tempez +11
Molybdenum disulfide (MoS) nanoribbons have attracted increased interest due to their properties which can be tailored by tuning their dimensions. Herein, we demonstrate the gr…
Nanoscale view of engineered massive Dirac quasiparticles in lithographic superstructures
Alfred J. H. Jones, Lene Gammelgaard, Mikkel O. Sauer +13
Massive Dirac fermions are low-energy electronic excitations characterized by a hyperbolic band dispersion. They play a central role in several emerging physical phenomena such as…
Programming moiré patterns in 2D materials by bending
Mäelle Kapfer, Bjarke S. Jessen, Megan E. Eisele +20
Moiré superlattices in twisted two-dimensional materials have generated tremendous excitement as a platform for achieving quantum properties on demand. However, the moiré pattern i…
Fermi Level Depinning in Two-Dimensional Materials Using a Fluorinated Bilayer Graphene Barrier
Cunzhi Sun, Cheng Xiang, Rongdun Hong +4
Strong Fermi level pinning (FLP) - often attributed to metal-induced gap states at the interfacial contacts - severely reduces the tunability of the Schottky barrier height of the…
