Detection of Individual Gas Molecules Absorbed on Graphene
TL;DR: Graphene is an exceptionally low-noise material electronically, which makes it a promising candidate not only for chemical detectors but also for other applications where local probes sensitive to external charge, magnetic field or mechanical strain are required.
Journal ArticleDOI
WSe2 Light-Emitting Tunneling Transistors with Enhanced Brightness at Room Temperature
Freddie Withers,O. Del Pozo-Zamudio,S. Schwarz,S. Dufferwiel,Paul M. Walker,T. Godde,A. P. Rooney,Ali Gholinia,Colin R. Woods,Peter Blake,Sarah J. Haigh,Kenji Watanabe,T. Taniguchi,Igor L. Aleiner,Andre K. Geim,Vladimir I. Fal'ko,Alexander I. Tartakovskii,K. S. Novoselov +17 more
TL;DR: It is shown that the EQE of WSe2 devices grows with temperature, with room temperature EQE reaching 5%, which is 250× more than the previous best performance of MoS2 and MoSe2 quantum wells in ambient conditions.
Journal ArticleDOI
Measuring Hall Viscosity of Graphene’s Electron Fluid
A. I. Berdyugin,Shuigang Xu,Francesco M. D. Pellegrino,Francesco M. D. Pellegrino,R. Krishna Kumar,Alessandro Principi,Iacopo Torre,M. Ben Shalom,T. Taniguchi,Kei Watanabe,Irina V. Grigorieva,Marco Polini,Marco Polini,Andre K. Geim,Denis A. Bandurin +14 more
TL;DR: In this paper, the authors found that the viscous electron fluid in graphene responds to nonquantizing magnetic fields by producing an electric field opposite to that generated by the ordinary Hall effect.
Journal ArticleDOI
Density of States and Zero Landau Level Probed through Capacitance of Graphene
Leonid Ponomarenko,R. Yang,Roman V. Gorbachev,Peter Blake,A. S. Mayorov,Kostya S. Novoselov,Mikhail I. Katsnelson,Andre K. Geim +7 more
TL;DR: Capacitors in which a finite electronic compressibility of graphene dominates the electrostatics, resulting in pronounced changes in capacitance as a function of magnetic field and carrier concentration are reported.
Journal ArticleDOI
Sieving hydrogen isotopes through two-dimensional crystals.
M. Lozada-Hidalgo,S. Hu,Owen P. Marshall,Artem Mishchenko,Alexander N. Grigorenko,Robert A. W. Dryfe,Boya Radha,Irina V. Grigorieva,Andre K. Geim +8 more
TL;DR: It is shown that monolayers of graphene and boron nitride can be used to separate hydrogen ion isotopes, and the demonstrated approach offers a competitive and scalable way for hydrogen isotope enrichment.
