Xiaobo Lu,Petr Stepanov,Wei Yang,Ming Xie,Mohammed Ali Aamir,Ipsita Das,C. Urgell,Kenji Watanabe,Takashi Taniguchi,Guangyu Zhang,Adrian Bachtold,Allan H. MacDonald,Dmitri K. Efetov +12 more
TL;DR: In this paper, the authors report the fabrication of magic-angle twisted bilayer graphene devices with highly uniform twist angles, which enables the observation of new superconducting domes, orbital magnets and Chern insulating states.
Journal ArticleDOI
Controlling electron-phonon interactions in graphene at ultrahigh carrier densities
Dmitri K. Efetov,Philip Kim +1 more
TL;DR: The density dependence of the characteristic temperature Θ( BG) defining the crossover between the two distinct regimes is mapped out, and it is shown that, for all n, ρ(T) scales as a universal function of the normalized temperature T/Θ(BG).
Journal ArticleDOI
Superconductivity and strong correlations in moiré flat bands
TL;DR: In this article, the status and prospects for flat-band engineering in van der Waals heterostructures and explore how both phenomena emerge from the moire flat bands are reviewed and discussed.
Journal ArticleDOI
Electronic transport and quantum hall effect in bipolar graphene p-n-p junctions.
Barbaros Özyilmaz,Pablo Jarillo-Herrero,Dmitri K. Efetov,Dmitry A. Abanin,Leonid Levitov,Philip Kim +5 more
TL;DR: A series of fractional quantum Hall conductance plateaus at high magnetic fields as the local charge density is varied in the p and n regions are observed, which exhibit sensitivity to interedge backscattering which is found to be strong for some of the plateaus and much weaker for other plateaus.
Journal ArticleDOI
Superconductors, Orbital Magnets, and Correlated States in Magic Angle Bilayer Graphene
Xiaobo Lu,Petr Stepanov,Wei Yang,Ming Xie,Mohammed Ali Aamir,Ipsita Das,C. Urgell,Kenji Watanabe,Takashi Taniguchi,Guangyu Zhang,Adrian Bachtold,Allan H. MacDonald,Dmitri K. Efetov +12 more
TL;DR: This study shows that broken-symmetry states, interaction-driven insulators, orbital magnets, states with non-zero Chern numbers and superconducting domes occur frequently across a wide range of moiré flat band fillings, including close to charge neutrality.
