Layer- and Gate-tunable Spin-Orbit Coupling in a High Mobility Few-Layer Semiconductor
D. Shcherbakov, P. Stepanov, S. Memaran +14
Spin-orbit coupling (SOC) is a relativistic effect, where an electron moving in an electric field experiences an effective magnetic field in its rest frame. In crystals without inv…
Equilibration and Filtering of Quantum Hall Edge States in Few-Layer Black Phosphorus
J. Yang, K. Wang, S. Che +9
We realize p-p'-p junctions in few-layer black phosphorus (BP) devices, and use magneto-transport measurements to study the equilibration and transmission of edge states at the int…
Helical Edge States and Quantum Phase Transitions in Tetralayer Graphene
Shi Che, Yanmeng Shi, Jiawei Yang +9
Helical conductors with spin-momentum locking are promising platforms for Majorana fermions. Here we report observation of two topologically distinct phases supporting helical edge…
Integer and Fractional Quantum Hall effect in Ultra-high Quality Few-layer Black Phosphorus Transistors
Jiawei Yang, Son Tran, Jason Wu +8
As a high mobility two-dimensional semiconductor with strong structural and electronic anisotropy, atomically thin black phosphorus (BP) provides a new playground for investigating…
Long-Distance Spin Transport Through a Graphene Quantum Hall Antiferromagnet
Petr Stepanov, Shi Che, Dmitry Shcherbakov +11
Antiferromagnetic insulators (AFMI) are robust against stray fields, and their intrinsic dynamics could enable ultrafast magneto-optics and ultrascaled magnetic information process…
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…
