Wigner solid pinning modes tuned by fractional quantum Hall states of a nearby layer
A. T. Hatke, H. Deng, Yang Liu +5
We study a bilayer system hosting exotic many-body states of two-dimensional electron systems (2DESs) in close proximity but isolated from one another by a thin barrier. One 2DES h…
Critical Filling Factor for the Formation of a Quantum Wigner Crystal Screened by a Nearby Layer
H. Deng, L. W. Engel, L. N. Pfeiffer +3
One of the most fascinating ground states of an interacting electron system is the so-called Wigner crystal where the electrons, in order to minimize their repulsive Coulomb energy…
Multivalley two-dimensional electron system in an AlAs quantum well with mobility exceeding cmVs
Yoon Jang Chung, K. A. Villegas Rosales, H. Deng +4
Degenerate conduction-band minima, or `valleys', in materials such as Si, AlAs, graphene, and MoS allow them to host two-dimensional electron systems (2DESs) that can access a…
Cyclotron Orbits of Composite Fermions in the Fractional Quantum Hall Regime
Insun Jo, Hao Deng, Yang Liu +4
We study a bilayer GaAs hole system that hosts two distinct many-body phases at low temperatures and high perpendicular magnetic fields. The higher-density (top) layer develops a F…
