Incipient Formation of the Reentrant Insulating Phase in a Dilute 2D Hole System with Strong Interactions
Richard L. J. Qiu, Chieh-Wen Liu, Andrew J. Woods +5
A new reentrant insulating phase (RIP) in low magnetic fields has been reported in the literature in strongly interacting 2D carrier systems and was suggested to be related to the…
Evidence for a New Intermediate Phase in a Strongly Correlated 2D System near Wigner Crystallization
R. L. J. Qiu, N. J. Goble, A. Serafin +6
How the two dimensional (2D) quantum Wigner crystal (WC) transforms into the metallic liquid phase remains to be an outstanding problem in physics. In theories considering the 2D W…
Connecting the Reentrant Insulating Phase and the Zero Field Metal-Insulator Transition in a 2D Hole System
Richard L. J. Qiu, Xuan P. A. Gao, L. N. Pfeiffer +1
We present the transport and capacitance measurements of 10nm wide GaAs quantum wells with hole densities around the critical point of the 2D metal-insulator transition (critical d…
Degenerate versus semi-degenerate transport in a correlated 2D hole system
Richard L. J. Qiu, Xuan P. A. Gao, Loren N. Pfeiffer +1
It has been puzzling that the resistivity of high mobility two-dimensional(2D) carrier systems in semiconductors with low carrier density often exhibits a large increase followed b…
