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…
Two-dimensional Transport Induced Linear Magneto-Resistance in Topological Insulator BiSe Nanoribbons
Hao Tang, Dong Liang, Richard L. J. Qiu +1
We report the study of a novel linear magneto-resistance (MR) under perpendicular magnetic fields in Bi2Se3 nanoribbons. Through angular dependence magneto-transport experiments, w…
