Optical Imaging of Flavor Order in Flat Band Graphene
Tian Xie, Tobias M. Wolf, Siyuan Xu +15
Spin and valley flavor polarization plays a central role in the many-body physics of flat band graphene, with fermi surface reconstructions often accompanied by quantized anomalous…
Gate-tunable topological phases in superlattice modulated bilayer graphene
Yongxin Zeng, Tobias M. R. Wolf, Chunli Huang +4
Superlattice potential modulation can produce flat minibands in Bernal-stacked bilayer graphene. In this work we study how band topology and interaction-induced symmetry-broken pha…
Electrical Reservoirs for Bilayer Excitons
Ming Xie, Allan H. MacDonald
The ground state of two-dimensional (2D) electron systems with equal low densities of electrons and holes in nearby layers is an exciton fluid. We show that a reservoir for exciton…
Transport studies of dual-gated ABC and ABA trilayer graphene: band gap opening and band structure tuning in very large perpendicular electric field
K. Zou, Fan Zhang, C. Clapp +2
We report on the transport properties of ABC and ABA stacked trilayer graphene using dual, locally gated field effect devices. The high efficiency and large breakdown voltage of th…
Transport Spectroscopy of Symmetry-Broken Insulating States in Bilayer Graphene
J. Velasco, L. Jing, W. Bao +11
The flat bands in bilayer graphene(BLG) are sensitive to electric fields E\bot directed between the layers, and magnify the electron-electron interaction effects, thus making BLG a…
