Correlated states of 2D electrons near the Landau level filling
Yoon Jang Chung, D. Graf, L. W. Engel +6
The ground state of two-dimensional electron systems (2DESs) at low Landau level filling factors () has long been a topic of interest and controversy in condensed mat…
Record-quality GaAs two-dimensional hole systems
Yoon Jang Chung, C. Wang, S. K. Singh +6
The complex band structure, large spin-orbit induced band splitting, and heavy effective mass of two-dimensional (2D) hole systems hosted in GaAs quantum wells render them rich pla…
Ultra-high quality two-dimensional electron systems
Yoon Jang Chung, K. A. Villegas-Rosales, K. W. Baldwin +4
Two-dimensional electrons confined to GaAs quantum wells are hallmark platforms for probing electron-electron interaction. Many key observations have been made in these systems as…
Heterostructure design to achieve high quality, high density GaAs 2D electron system with -factor tending to zero
Yoon Jang Chung, S. Yuan, Yang Liu +4
Hydrostatic pressure is a useful tool that can tune several key parameters in solid state materials. For example, the Landé -factor in GaAs two-dimensional electron systems (2DE…
Working principles of doping-well structures for high-mobility two-dimensional electron systems
Yoon Jang Chung, K. A. Villegas Rosales, K. W. Baldwin +3
Suppressing electron scattering is essential to achieve high-mobility two-dimensional electron systems (2DESs) that are clean enough to probe exotic interaction-driven phenomena. I…
Spatial Mapping of Local Density Variations in Two-dimensional Electron Systems Using Scanning Photoluminescence
Yoon Jang Chung, Kirk W. Baldwin, Kenneth W. West +4
We have developed a scanning photoluminescence technique that can directly map out the local two-dimensional electron density with a relative accuracy of cm$^{-…
