Magnetic-Field-Induced Hybridization of Electron Subbands in a Coupled Double Quantum Well
V. T. Dolgopolov, G. E. Tsydynzhapov, A. A. Shashkin +6
We employ a magnetocapacitance technique to study the spectrum of the soft two-subband (or double-layer) electron system in a parabolic quantum well with a narrow tunnel barrier in…
High Bias Transport and Magnetometer Design in Open Quantum Dots
M. Switkes, A. G. Huibers, C. M. Marcus +2
We report transport measurements as a function of bias in open semiconductor quantum dots. These measurements are well described by an effective electron temperature derived from J…
Mesoscopic Fluctuations of Elastic Cotunneling in Coulomb Blockaded Quantum Dots
S. M. Cronenwett, S. R. Patel, C. M. Marcus +2
We report measurements of mesoscopic fluctuations of elastic cotunneling in Coulomb blockaded quantum dots. Unlike resonant tunneling on Coulomb peaks, cotunneling in the valleys i…
Parallel Quantum-Point-Contacts as High-Frequency-Mixers
A. G. C. Haubrich, D. A. Wharam, H. Kriegelstein +4
We present the results of high-frequency mixing experiments performed upon parallel quantum point-contacts defined in the two-dimensional electron gas of an Al_{x}Ga_{1-x}As/GaAs-h…
Classical Advection of Guiding Centers in a Random Magnetic Field
L. Zielinski, K. Chaltikian, K. Birnbaum +3
We investigate theoretically and experimentally classical advective transport in a 2D electron gas in a random magnetic field. For uniform external perpendicular magnetic fields la…
Optical Response of Grating-Coupler-Induced Intersubband Resonances: The Role of Wood's Anomalies
L. Wendler, T. Kraft, M. Hartung +5
Grating-coupler-induced collective intersubband transitions in a quasi-two-dimensional electron system are investigated both experimentally and theoretically. Far-infrared transmis…
