Broken Symmetry Quantum Hall States in Dual Gated ABA Trilayer Graphene
Yongjin Lee, Jairo Velasco, David Tran +6
We present low temperature transport measurements on dual-gated suspended trilayer graphene in the quantum Hall (QH) regime. We observe QH plateaus at filling factors ν=-8, -2, 2,…
Quantum transport in double-gated graphene devices
J. Velasco, Y. Lee, L. Jing +3
Double-gated graphene devices provide an important platform for understanding electrical and optical properties of graphene. Here we present transport measurements of single layer,…
Visualizing Electrical Breakdown and ON/OFF States in Electrically Switchable Suspended Graphene Break Junctions
Hang Zhang, Wenzhong Bao, Zeng Zhao +8
Narrow gaps are formed in suspended single to few layer graphene devices using a pulsed electrical breakdown technique. The conductance of the resulting devices can be programmed b…
Minimum Conductivity and Evidence for Phase Transitions in Ultra-clean Bilayer Graphene
Wenzhong Bao, Jairo Velasco, Fan Zhang +6
Bilayer graphene (BLG) at the charge neutrality point (CNP) is strongly susceptible to electronic interactions, and expected to undergo a phase transition into a state with spontan…
