Jiwoong Park,Jiwoong Park,Abhay Pasupathy,Jonas I. Goldsmith,Connie Chang,Yuval Yaish,Jason R. Petta,Marie Rinkoski,James P. Sethna,Héctor D. Abruña,Paul L. McEuen,Daniel C. Ralph +11 more
TL;DR: Two related molecules containing a Co ion bonded to polypyridyl ligands, attached to insulating tethers of different lengths are examined, enabling the fabrication of devices that exhibit either single-electron phenomena, such as Coulomb blockade or the Kondo effect.
Journal ArticleDOI

TL;DR: Findings show that chemical doping is a promising route to achieving high-quality graphene films with a large carrier concentration.
Journal ArticleDOI
Maximized electron interactions at the magic angle in twisted bilayer graphene
Alexander Kerelsky,L. J. McGilly,Dante M. Kennes,Lede Xian,Matthew Yankowitz,Shaowen Chen,Kenji Watanabe,T. Taniguchi,James Hone,Cory Dean,Angel Rubio,Abhay Pasupathy +11 more
TL;DR: Scanning tunnelling spectroscopy is used to map the atomic-scale electronic structure of magic-angle twisted bilayer graphene, finding multiple signatures of electron correlations and thus providing insight into the sought-after mechanism behind superconductivity in graphene.

Alexander Kerelsky,L. J. McGilly,Dante M. Kennes,Lede Xian,Matthew Yankowitz,Shaowen Chen,Kenji Watanabe,T. Taniguchi,James Hone,Cory Dean,Angel Rubio,Abhay Pasupathy +11 more
TL;DR: In this paper, the atomic-scale structural and electronic properties of twisted bilayer graphene (TBLG) near the magic angle using scanning tunneling microscopy and spectroscopy (STM/STS).
Journal ArticleDOI
The Kondo effect in the presence of ferromagnetism.
Abhay Pasupathy,Radoslaw C. Bialczak,J. Martinek,Jacob E. Grose,Luke A. K. Donev,Paul L. McEuen,Daniel C. Ralph +6 more
TL;DR: Kondo correlations persisted despite the presence of ferromagnetism, but the Kondo peak in the differential conductance was split by an amount that decreased as the moments in the two electrodes were turned from parallel to antiparallel alignment.
