Journal ArticleDOI
Topological engineering of terahertz light using electrically tunable exceptional point singularities
M. Said Ergoktas,Sina Soleymani,Nurbek Kakenov,Kaiyuan Wang,Thomas B. Smith,Gokhan Bakan,Sinan Balci,Alessandro Principi,Kostya S. Novoselov,Sahin Kaya Ozdemir,Coskun Kocabas +10 more
TL;DR: Ergoktas et al. as mentioned in this paper demonstrated the emergence of EPs in an electrically controlled interaction between light and a collection of organic molecules in the terahertz regime at room temperature.
Journal ArticleDOI
Graphene-based papers as substrates for cell growth: Characterisation and impact on mammalian cells
Dhifaf A. Jasim,Neus Lozano,Cyrill Bussy,Irina Barbolina,Artur Filipe Rodrigues,Kostya S. Novoselov,Kostas Kostarelos +6 more
TL;DR: The fabrication and use of different oxidised graphene-based ‘papers’ as substrates for cell culture, using starting materials of different thickness and lateral dimensions suggest that substrates based on graphite and graphene oxide papers are suitable biocompatible cellular supports for anchorage-dependent cell growth.
Journal ArticleDOI
Coexistence of electron and hole transport in graphene
Steffen Wiedmann,H. J. van Elferen,E. V. Kurganova,Mikhail I. Katsnelson,A. J. M. Giesbers,A. Veligura,van Bart Wees,Roman V. Gorbachev,Kostya S. Novoselov,Jan C. Maan,Uli Zeitler +10 more
TL;DR: Using a two-component model of coexisting electrons and holes around the charge neutrality point, the authors unambiguously show that both types of carriers are simultaneously present in a quantum Hall metal state at nu = 0.
Journal ArticleDOI

Julien Barrier,Piranavan Kumaravadivel,Roshan Krishna-Kumar,Leonid Ponomarenko,Na Xin,Matthew Holwill,Ciaran Mullan,Minsoo Kim,Roman V. Gorbachev,Michael Thompson,Jonathan Prance,T. Taniguchi,Kenji Watanabe,Irina V. Grigorieva,Kostya S. Novoselov,Artem Mishchenko,Vladimir I. Fal'ko,Andre K. Geim,A. I. Berdyugin +18 more
TL;DR: It is shown that, in graphene-on-boron-nitride superlattices, Brown-Zak fermions can exhibit mobilities above 106 cm2 V−1 s−1 and the mean free path exceeding several micrometers and all the degeneracies (spin, valley and mini-valley) can be lifted by exchange interactions below 1 K.
Journal ArticleDOI
Excess resistivity in graphene superlattices caused by umklapp electron-electron scattering
John Wallbank,R. Krishna Kumar,Matthew Holwill,Zihao Wang,Gregory Auton,John Birkbeck,Artem Mishchenko,Leonid Ponomarenko,Kenji Watanabe,Takashi Taniguchi,Kostya S. Novoselov,Igor L. Aleiner,Andre K. Geim,Vladimir I. Fal'ko +13 more
TL;DR: In this paper, electron-electron umklapp scattering dominates the transport properties of graphene-on-boron-nitride superlattices over a wide range of temperatures and carrier densities.
