Electric field tunable exchange interaction in InAs/GaAs coupled quantum dots
Kushal C. Wijesundara, Mauricio Garrido, Swati Ramanathan +4
Spin manipulation in coupled quantum dots is of interest for quantum information applications. Control of the exchange interaction between electrons and holes via an applied electr…
Characterization of the Shell Structure in Coupled Quantum Dots through Resonant Optical Probing
Mauricio Garrido, Kushal C. Wijesundara, Swati Ramanathan +4
Excited states in single quantum dots (QDs) have been shown to be useful for spin state initialization and manipulation. For scalable quantum information processing it is necessary…
Photoluminescence Spectroscopy of the Molecular Biexciton in Vertically Stacked Quantum Dot Pairs
M. Scheibner, I. V. Ponomarev, E. A. Stinaff +5
We present photoluminescence studies of the molecular neutral biexciton-exciton spectra of individual vertically stacked InAs/GaAs quantum dot pairs. We tune either the hole or the…
Electrically tunable g-factors in quantum dot molecular spin states
M. F. Doty, M. Scheibner, I. V. Ponomarev +5
We present a magneto-photoluminescence study of individual vertically stacked InAs/GaAs quantum dot pairs separated by thin tunnel barriers. As an applied electric field tunes the…
Polarized fine structure in the excitation spectrum of a negatively charged quantum dot
M. E. Ware, E. A. Stinaff, D. Gammon +7
We report polarized photoluminescence excitation spectroscopy of the negative trion in single charge tunable InAs/GaAs quantum dots. The spectrum exhibits a p-shell resonance with…
Optical pumping of electronic and nuclear spin in single charge-tunable quantum dots
A. S. Bracker, E. A. Stinaff, D. Gammon +8
We present a comprehensive examination of optical pumping of spins in individual GaAs quantum dots as we change the charge from positive to neutral to negative using a Schottky dio…
