Journal ArticleDOI
Dimensional reduction, quantum Hall effect and layer parity in graphite films
Jun Yin,Sergey Slizovskiy,Yang Cao,Yang Cao,S. Hu,S. Hu,Yaping Yang,Inna I. Lobanova,Benjamin A. Piot,Seok-Kyun Son,Servet Ozdemir,Takashi Taniguchi,Kenji Watanabe,Kostya S. Novoselov,Francisco Guinea,Francisco Guinea,Andre K. Geim,Vladimir I. Fal'ko,Vladimir I. Fal'ko,Artem Mishchenko +19 more
TL;DR: The quantum Hall effect (QHE) originates from discrete Landau levels forming in a two-dimensional electron system in a magnetic field as mentioned in this paper, which is forbidden in three dimensions because the third dimension spreads Landau level into overlapping bands, destroying the quantization.
Journal ArticleDOI
Upconverted electroluminescence via Auger scattering of interlayer excitons in van der Waals heterostructures.
J. Binder,James Howarth,Freddie Withers,Maciej R. Molas,Maciej R. Molas,Takashi Taniguchi,Kenji Watanabe,Clément Faugeras,Andrzej Wysmołek,Mark Danovich,Vladimir I. Fal'ko,Vladimir I. Fal'ko,Andre K. Geim,Konstantin S. Novoselov,Marek Potemski,Marek Potemski,Aleksey Kozikov +16 more
TL;DR: In this paper, a large population of typical optically silent interlayer excitons is established by electrically injecting carriers into WSe2/MoS2 type-II heterostructures which are indirect in real and k-space.
Journal ArticleDOI
Cascaded Optical Field Enhancement in Composite Plasmonic Nanostructures
Vasyl G. Kravets,G. Zoriniants,C. P. Burrows,Fred Schedin,Cinzia Casiraghi,Philipp Klar,Andre K. Geim,William L. Barnes,Alexander N. Grigorenko +8 more
TL;DR: In this article, a set of metallic nanodisks placed one above another was used to achieve a cascaded enhancement of the Raman signal at optical frequencies, and the optical properties of reproducible arrays of these structures were studied using scanning confocal Raman spectroscopy.
Journal ArticleDOI
Stacking Order in Graphite Films Controlled by van der Waals Technology.
Yaping Yang,Yichao Zou,Colin R. Woods,Yanmeng Shi,Jun Yin,Shuigang Xu,Servet Ozdemir,Takashi Taniguchi,Kenji Watanabe,Andre K. Geim,Kostya S. Novoselov,Sarah J. Haigh,Artem Mishchenko +12 more
TL;DR: It is found that hBN-encapsulation which is introduced parallel to the graphite zigzag edges preserves ABC stacking, while encapsulation along the armchair edges transforms the stacking to ABA.
Journal ArticleDOI
Control of electron-electron interaction in graphene by proximity screenings.
Minsoo Kim,Shuigang Xu,A. I. Berdyugin,Alessandro Principi,Sergey Slizovskiy,Na Xin,Piranavan Kumaravadivel,Wenjun Kuang,Matthew J. Hamer,R. Krishna Kumar,Roman V. Gorbachev,Kei Watanabe,T.

TL;DR: Control the interactions by proximity screening with gate dielectrics of nanometer thickness, revealing qualitative changes in concentration and temperature dependences, and validating their analysis using electron hydrodynamics and umklapp scattering approaches.
