High resolution nuclear magnetic resonance spectroscopy of highly-strained quantum dot nanostructures
E. A. Chekhovich, K. V. Kavokin, J. Puebla +7
Much new solid state technology for single-photon sources, detectors, photovoltaics and quantum computation relies on the fabrication of strained semiconductor nanostructures. Succ…
Isotope sensitive measurement of the hole-nuclear spin interaction in quantum dots
E. A. Chekhovich, A. B. Krysa, M. Hopkinson +4
Decoherence caused by nuclear field fluctuations is a fundamental obstacle to the realization of quantum information processing using single electron spins. Alternative proposals h…
Charge control in InP/GaInP single quantum dots embedded in Schottky diodes
O. D. D. Couto, J. Puebla, E. A. Chekhovich +6
We demonstrate control by applied electric field of the charge states in single self-assembled InP quantum dots placed in GaInP Schottky structures grown by metalorganic vapor phas…
Full coherent control of nuclear spins in an optically pumped single quantum dot
M. N. Makhonin, K. V. Kavokin, P. Senellart +4
Highly polarized nuclear spins within a semiconductor quantum dot (QD) induce effective magnetic (Overhauser) fields of up to several Tesla acting on the electron spin or up to a f…
Stark Spectroscopy and Radiative Lifetimes in Single Self-Assembled CdTe Quantum Dots
Łukasz Kłopotowski, Valia Voliotis, Arkadiusz Kudelski +8
We present studies on Coulomb interactions in single self-assembled CdTe quantum dots. We use a field effect structure to tune the charge state of the dot and investigate the impac…
