Long wavelength local density of states oscillations near graphene step edges
Jiamin Xue, Javier Sanchez-Yamagishi, K. Watanabe +3
Using scanning tunneling microscopy and spectroscopy, we have studied the local density of states (LDOS) of graphene over step edges in boron nitride. Long wavelength oscillations…
Quantum Hall Effect, Screening and Layer-Polarized Insulating States in Twisted Bilayer Graphene
Javier D. Sanchez-Yamagishi, Thiti Taychatanapat, Kenji Watanabe +3
We investigate electronic transport in dual-gated twisted bilayer graphene. Despite the sub-nanometer proximity between the layers, we identify independent contributions to the mag…
Flow-History-Dependent Behavior in Entangled Polymer Melt Flow with Multiscale Simulation
Takahiro Murashima, Takashi Taniguchi
Polymer melts represent the flow-history-dependent behavior. To clearly show this behavior, we have investigated flow behavior of an entangled polymer melt around two cylinders pla…
Hot Carrier-Assisted Intrinsic Photoresponse in Graphene
Nathaniel M. Gabor, Justin C. W. Song, Qiong Ma +6
Graphene is a new material showing high promise in optoelectronics, photonics, and energy-harvesting applications. However, the underlying physical mechanism of optoelectronic resp…
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…
Giant Nonlocality near the Dirac Point in Graphene
D. A. Abanin, S. V. Morozov, L. A. Ponomarenko +8
Transport measurements have been a powerful tool for uncovering new electronic phenomena in graphene. We report nonlocal measurements performed in the Hall bar geometry with voltag…
