Tunable Inter-Moiré Physics in Consecutively-Twisted Trilayer Graphene
Wei Ren, Konstantin Davydov, Ziyan Zhu +6
We fabricate a twisted trilayer graphene device with consecutive twist angles of 1.33 and 1.64 degrees, in which we electrostatically tune the electronic states from each of the tw…

Selective Manipulation and Tunneling Spectroscopy of Broken-Symmetry Quantum Hall States in a Hybrid-edge Quantum Point Contact
Wei Ren, Xi Zhang, Jaden Ma +4
We present a device architecture of hybrid-edge and dual-gated quantum point contact. We demonstrate improved electrostatic control over the separation, position, and coupling of e…
