Tunable Lifshitz Transitions and Multiband Transport in Tetralayer Graphene
Yanmeng Shi, Shi Che, Kuan Zhou +8
As the Fermi level and band structure of two-dimensional materials are readily tunable, they constitute an ideal platform for exploring Lifshitz transition, a change in the topolog…
Surface Transport and Quantum Hall Effect in Ambipolar Black Phosphorus Double Quantum Wells
Son Tran, Jiawei Yang, Nathaniel Gillgren +10
Quantum wells constitute one of the most important classes of devices in the study of 2D systems. In a double layer QW, the additional "which-layer" degree of freedom gives rise to…
Weak Localization and Electron-electron Interactions in Few Layer Black Phosphorus Devices
Yanmeng Shi, Nathaniel Gillgren, Timothy Espiritu +5
Few layer phosphorene(FLP) devices are extensively studied due to its unique electronic properties and potential applications on nano-electronics . Here we present magnetotransport…
Tunable symmetries of integer and fractional quantum Hall phases in heterostructures with multiple Dirac bands
Petr Stepanov, Yafis Barlas, Tim Espiritu +5
The co-presence of multiple Dirac bands in few-layer graphene leads to a rich phase diagram in the quantum Hall regime. Using transport measurements, we map the phase diagram of BN…
Energy gaps and layer polarization of integer and fractional quantum Hall states in bilayer graphene
Yanmeng Shi, Yongjin Lee, Shi Che +6
Owing to the spin, valley, and orbital symmetries, the lowest Landau level (LL) in bilayer graphene exhibits multicomponent quantum Hall ferromagnetism. Using transport spectroscop…
Gate Tunable Quantum Oscillations in Air-Stable and High Mobility Few-Layer Phosphorene Heterostructures
Nathaniel Gillgren, Darshana Wickramaratne, Yanmeng Shi +12
As the only non-carbon elemental layered allotrope, few-layer black phosphorus or phosphorene has emerged as a novel two-dimensional (2D) semiconductor with both high bulk mobility…
