Collection of indirect excitons in a diamond-shaped electrostatic trap
A. A. High, A. K. Thomas, G. Grosso +7
We report on the principle and realization of a new trap for excitons -- the diamond electrostatic trap -- which uses a single electrode to create a confining potential for exciton…
Localization-Delocalization Transition of Indirect Excitons in Lateral Electrostatic Lattices
M. Remeika, J. C. Graves, A. T. Hammack +5
We study transport of indirect excitons in GaAs/AlGaAs coupled quantum wells in linear lattices created by laterally modulated gate voltage. The localization-delocalization transit…
Measurement of Temporal Correlations of the Overhauser Field in a Double Quantum Dot
D. J. Reilly, J. M. Taylor, E. A. Laird +4
In quantum dots made from materials with nonzero nuclear spins, hyperfine coupling creates a fluctuating effective Zeeman field (Overhauser field) felt by electrons, which can be a…
Dynamic Nuclear Polarization with Single Electron Spins
J. R. Petta, J. M. Taylor, A. C. Johnson +5
We polarize nuclear spins in a GaAs double quantum dot by controlling two-electron spin states near the anti-crossing of the singlet (S) and m_S=+1 triplet (T+) using pulsed gates.…
Fast Single-Charge Sensing with an rf Quantum Point Contact
D. J. Reilly, C. M. Marcus, M. P. Hanson +1
We report high-bandwidth charge sensing measurements using a GaAs quantum point contact embedded in a radio frequency impedance matching circuit (rf-QPC). With the rf-QPC biased ne…
Hyperfine-mediated gate-driven electron spin resonance
E. A. Laird, C. Barthel, E. I. Rashba +3
An all-electrical spin resonance effect in a GaAs few-electron double quantum dot is investigated experimentally and theoretically. The magnetic field dependence and absence of ass…
