Experimental evidence for orbital magnetic moments generated by moiré-scale current loops in twisted bilayer graphene
Si-Yu Li, Yu Zhang, Ya-Ning Ren +3
A remarkable property of twisted bilayer graphene (TBG) with small twist angle is the presence of a well-defined and conserved low-energy valley degrees of freedom1, which can pote…
Spectroscopic evidence for a spin and valley polarized metallic state in a non-magic-angle twisted bilayer graphene
Ya-Ning Ren, Chen Lu, Yu Zhang +7
In the magic-angle twisted bilayer graphene (MA-TBG), strong electron-electron (e-e) correlations caused by the band-flattening lead to many exotic quantum phases such as supercond…
Mesoscopic Electronic Transport in Twisted Bilayer Graphene
Yulei Han, Yafei Ren, Xinlong Dong +3
We numerically investigate the electronic transport properties between two mesoscopic graphene disks with a twist by employing the density functional theory coupled with non-equili…
Scanning tunneling microscope characterizations of a circular graphene resonator realized with p-p junctions
Ya-Ning Ren, Jiao-Jiao Zhou, Zhong-Qiu Fu +11
Using low-temperature high-magnetic-field scanning tunneling microscopy and spectroscopy (STM/STS), we systematically study a graphene quantum dot (GQD) defined by a circular graph…
Metallic Network of Topological Domain Walls
Tao Hou, Yafei Ren, Yujie Quan +3
We study the electronic and transport properties of a network of domain walls between insulating domains with opposite valley Chern numbers. We find that the network is semi-metall…
