Resistance Fluctuations in Composite Fermion State near Landau Level Filling Factor in A Square Quantum Well
Jian Zhang, R. R. Du, J. A. Simmons +1
We have studied the magnetotransport near Landau level filling factor in a GaAs-Al0.3Ga0.7As square quantum well (width 35 nm) in magnetic field up to 42 T and in a temper…
Hysteresis in the quantum Hall regimes in electron double quantum well structures
W. Pan, J. L. Reno, J. A. Simmons
We present in this paper experimental results on the transport hysteresis in electron double quantum well structures. Exploring the measurement technique of fixing the magnetic fie…
Observation of a node in the quantum oscillations induced by microwave radiation
Alexey E. Kovalev, Sergey A. Zvyagin, Clifford R. Bowers +2
The microwave induced magnetoresistance in GaAs/AlGaAs heterostructure was studied at temperatures below 1K and frequencies in the range of 150-400 GHz. A distinct node in the Shub…
Oscillatory Magneto-Thermopower and Resonant Phonon Drag in a High-Mobility 2D Electron Gas
Jian Zhang, S. K. Lyo, R. R. Du +2
Experimental and theoretical evidence is presented for new low-magnetic-field ( kG) 1/B-oscillations in the thermoelectric power of a high-mobility GaAs/AlGaAs two-dimensional…
Linear temperature dependence of conductivity in the "insulating" regime of dilute two-dimensional holes in GaAs
Hwayong Noh, M. P. Lilly, D. C. Tsui +3
The conductivity of extremely high mobility dilute two-dimensional holes in GaAs changes linearly with temperature in the insulating side of the metal-insulator transition. Hopping…
Resistivity of dilute 2D electrons in an undoped GaAs heterostructure
M. P. Lilly, J. L. Reno, J. A. Simmons +6
We report resistivity measurements from 0.03 K to 10 K in a dilute high mobility 2D electron system. Using an undoped GaAs/AlGaAs heterojunction in a gated field-effect transistor…
