Rewritable Complementary Nanoelectronics Enabled by Electron-Beam Programmable Ambipolar Doping
Qing Lan, Wenqing Song, Siyin Zhu +13
The ability to reversibly and site-selectively tune ambipolar doping in a single semiconductor is crucial for reconfigurable electronics beyond silicon, but remains highly challeng…
Imaging Tunable Luttinger Liquid Systems in van der Waals Heterostructures
Hongyuan Li, Ziyu Xiang, Tianle Wang +16
One-dimensional (1D) interacting electrons are often described as a Luttinger liquid1-4 having properties that are intrinsically different from Fermi liquids in higher dimensions5,…
Wigner Molecular Crystals from Multi-electron Moiré Artificial Atoms
Hongyuan Li, Ziyu Xiang, Aidan P. Reddy +10
Semiconductor moiré superlattices provide a versatile platform to engineer new quantum solids composed of artificial atoms on moiré sites. Previous studies have mostly focused on t…
Imaging Moiré Excited States with Photocurrent Tunneling Microscopy
Hongyuan Li, Ziyu Xiang, Mit H. Naik +12
Moiré superlattices provide a highly tunable and versatile platform to explore novel quantum phases and exotic excited states ranging from correlated insulators1-17 to moiré excito…
Spatially resolving density-dependent screening around a single charged atom in graphene
Dillon Wong, Fabiano Corsetti, Yang Wang +8
Electrons in two-dimensional graphene sheets behave as interacting chiral Dirac fermions and have unique screening properties due to their symmetry and reduced dimensionality. By u…
Controlled Growth of a Line Defect in Graphene and Implications for Gate-Tunable Valley Filtering
J. -H. Chen, G. Autès, N. Alem +7
Atomically precise tailoring of graphene can enable unusual transport pathways and new nanometer-scale functional devices. Here we describe a recipe for the controlled production o…
Electronic and plasmonic phenomena at graphene grain boundaries
Z. Fei, A. S. Rodin, W. Gannett +13
Graphene, a two-dimensional honeycomb lattice of carbon atoms, is of great interest in (opto)electronics and plasmonics and can be obtained by means of diverse fabrication techniqu…
Atomically perfect torn graphene edges and their reversible reconstruction
Kwanpyo Kim, Sinisa Coh, C. Kisielowski +4
The atomic structure of graphene edges is critical in determining the electrical, magnetic, and chemical properties of truncated graphene structures, notably nanoribbons. Unfortuna…
Experimentally Engineering the Edge Termination of Graphene Nanoribbons
Xiaowei Zhang, Oleg V. Yazyev, Juanjuan Feng +9
The edges of graphene nanoribbons (GNRs) have attracted much interest due to their potentially strong influence on GNR electronic and magnetic properties. Here we report the abilit…
Raman spectroscopy study of rotated double-layer graphene: Misorientation-angle dependence of electronic structure
Kwanpyo Kim, Sinisa Coh, Liang Z. Tan +7
We present a systematic Raman study of unconventionally-stacked double-layer graphene, and find that the spectrum strongly depends on the relative rotation angle between layers. Ro…
Boron Nitride Substrates for High Mobility Chemical Vapor Deposited Graphene
W. Gannett, W. Regan, K. Watanabe +3
Chemical vapor deposited (CVD) graphene is often presented as a scalable solution to graphene device fabrication, but to date such graphene has exhibited lower mobility than that p…
Multiply Folded Graphene
Kwanpyo Kim, Zonghoon Lee, Brad Malone +7
The folding of paper, hide, and woven fabric has been used for millennia to achieve enhanced articulation, curvature, and visual appeal for intrinsically flat, two-dimensional mate…
An Atomic-resolution nanomechanical mass sensor
K. Jensen, Kwanpyo Kim, A. Zettl
Mechanical resonators are widely used as inertial balances to detect small quantities of adsorbed mass through shifts in oscillation frequency[1]. Advances in lithography and mater…
