Journal ArticleDOI
Ultra-thin van der Waals crystals as semiconductor quantum wells
Johanna Zultak,Samuel Magorrian,Maciej Koperski,Alistair Garner,Matthew J. Hamer,Endre Tóvári,Kostya S. Novoselov,Alexander Zhukov,Yichao Zou,Neil R. Wilson,Sarah J. Haigh,Andrey V. Kretinin,Vladimir I. Fal'ko,Roman V. Gorbachev +13 more
TL;DR: In this article, the full subbands structure of a van der Waals heterostructures were revealed by studying resonance features in the tunnelling current, photo absorption and light emission.
Journal ArticleDOI
Layer-engineered interlayer excitons
Qing-Hai Tan,Abdullah Rasmita,Si Li,Si Li,Sheng Liu,Zumeng Huang,Qihua Xiong,Shengyuan A. Yang,Kostya S. Novoselov,Weibo Gao +9 more
TL;DR: In this article, the authors show that photoluminescence from excitons can be recovered by engineering multilayer heterostructures, with the band transition reserved to be a direct type.
Journal ArticleDOI
Scanning gate microscopy on a graphene quantum point contact
TL;DR: In this paper, a scanning gate microscopy (SGM) measurements on a graphene point contact was carried out under ambient conditions, which showed that the resistance of the point contact is strongly affected by the electric field of the tip at the position of the QPC.
Journal ArticleDOI
Direct Observation of Incommensurate-Commensurate Transition in Graphene-hBN Heterostructures via Optical Second Harmonic Generation.
E. A. Stepanov,E. A. Stepanov,Sergey Semin,Colin R. Woods,M. Vandelli,Alexey Kimel,Kostya S. Novoselov,Mikhail I. Katsnelson,Mikhail I. Katsnelson +8 more
TL;DR: In this paper, the authors use optical second harmonic generation (OSG) to investigate the alignment of graphene/hexagonal boron nitride heterostructures and find that this structural change in the system can be directly observed via a strong modification of a nonlinear optical signal.
Journal ArticleDOI
Supercurrent and multiple Andreev reflections in micrometer-long ballistic graphene Josephson junctions
Mengjian Zhu,Mengjian Zhu,Moshe Ben Shalom,Artem Mishchsenko,Vladimir I. Fal'ko,Kostya S. Novoselov,Andre K. Geim +6 more
TL;DR: Electrical transport measurements on ballistic superconductor-graphene-superconductor junctions are demonstrated by contacting graphene to niobium with a junction length up to 1.5 μm, demonstrating the ballistic propagation in the junctions.
