Journal ArticleDOI
Electronic Properties of Graphene Encapsulated with Different Two-Dimensional Atomic Crystals
Andrey V. Kretinin,Yang Cao,J. S. Tu,Geliang Yu,Rashid Jalil,Kostya S. Novoselov,Sarah J. Haigh,Ali Gholinia,Artem Mishchenko,M. Lozada,Thanasis Georgiou,Colin R. Woods,Freddie Withers,Peter Blake,Goki Eda,A. Wirsig,C. Hucho,Kenji Watanabe,T. Taniguchi,Andre K. Geim,Roman V. Gorbachev +20 more
TL;DR: This work reports on the search for alternative substrates for making quality graphene heterostructures using atomically flat crystals and attributes the difference mainly to self-cleansing that takes place at interfaces between graphene, hBN, and transition metal dichalcogenides.
Journal ArticleDOI
Twist-controlled resonant tunnelling in graphene/boron nitride/graphene heterostructures
Artem Mishchenko,J. S. Tu,Y. Cao,Roman V. Gorbachev,John Wallbank,Mark Greenaway,V. E. Morozov,Sergey V. Morozov,Mengjian Zhu,Swee Liang Wong,Freddie Withers,Colin R. Woods,Y-J Kim,Kenji Watanabe,T. Taniguchi,E. E. Vdovin,Oleg Makarovsky,T. M. Fromhold,Vladimir I. Fal'ko,Andre K. Geim,Laurence Eaves,Konstantin S. Novoselov +21 more
TL;DR: It is demonstrated how careful alignment of the crystallographic orientation of two graphene electrodes separated by a layer of hexagonal boron nitride in a transistor device can achieve resonant tunnelling with conservation of electron energy, momentum and, potentially, chirality.
Journal ArticleDOI
Hierarchy of Hofstadter states and replica quantum Hall ferromagnetism in graphene superlattices
Geliang Yu,Roman V. Gorbachev,J. S. Tu,Andrey V. Kretinin,Yang Cao,Rashid Jalil,Freddie Withers,Leonid Ponomarenko,Leonid Ponomarenko,Benjamin A. Piot,Marek Potemski,D. C. Elias,D. C. Elias,Xi Chen,Kazuyuki Watanabe,Takashi Taniguchi,Irina V. Grigorieva,K. S. Novoselov,Vladimir I. Fal'ko,Andre K. Geim,Artem Mishchenko +20 more
TL;DR: In this article, the Hofstadter butterfly is suppressed by suppression of quantum Hall antiferromagnetism at particular commensurate magnetic fluxes by means of capacitance spectroscopy.
Journal ArticleDOI
Tuning the valley and chiral quantum state of Dirac electrons in van der Waals heterostructures
John Wallbank,Davit Ghazaryan,Abhishek Kumar Misra,Y. Cao,J. S. Tu,Benjamin A. Piot,Marek Potemski,Sergio Pezzini,Steffen Wiedmann,Uli Zeitler,Thomas Lane,Sergey V. Morozov,Sergey V. Morozov,Mark Greenaway,Laurence Eaves,Laurence Eaves,Andre K. Geim,Vladimir I. Fal'ko,K. S. Novoselov,Artem Mishchenko +19 more
TL;DR: The direct observation and manipulation of chirality and pseudospin polarization in the tunneling of electrons between two almost perfectly aligned graphene crystals are reported and a technique for preparing graphene’s Dirac electrons in a particular quantum chiral state in a selected valley is demonstrated.
