Melting phase diagram of bubble phases in high Landau levels
K. A. Villegas, S. K. Singh, H. Deng +5
A low-disorder, two-dimensional electron system (2DES) subjected to a large perpendicular magnetic field and cooled to very low temperatures provides a rich platform for studies of…
Thermal and quantum melting phase diagrams for a magnetic-field-induced Wigner solid
Meng K. Ma, K. A. Villegas Rosales, H. Deng +6
A sufficiently large perpendicular magnetic field quenches the kinetic (Fermi) energy of an interacting two-dimensional (2D) system of fermions, making them susceptible to the form…
Probing the Melting of a Two-dimensional Quantum Wigner Crystal via its Screening Efficiency
H. Deng, L. N. Pfeiffer, K. W. West +3
One of the most fundamental and yet elusive collective phases of an interacting electron system is the quantum Wigner crystal (WC), an ordered array of electrons expected to form w…
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…
