Engineering electron and hole tunneling with asymmetric InAs quantum dot molecules
A. S. Bracker, M. Scheibner, M. F. Doty +6
Most self-assembled quantum dot molecules are intrinsically asymmetric with inequivalent dots resulting from imperfect control of crystal growth. We have grown vertically-aligned p…
Electrical control of optical orientation of neutral and negatively charged excitons in n-type semiconductor quantum well
R. I. Dzhioev, V. L. Korenev, M. V. Lazarev +3
We report a giant electric field induced increase of spin orientation of excitons in n-type GaAs/AlGaAs quantum well. It correlates strongly with the formation of negatively charge…
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…
Spin Fine Structure in Optically Excited Quantum Dot Molecules
M. Scheibner, M. F. Doty, I. V. Ponomarev +5
The interaction between spins in coupled quantum dots is revealed in distinct fine structure patterns in the measured optical spectra of InAs/GaAs double quantum dot molecules cont…
Internal transitions of quasi-2D charged magneto-excitons in the presence of purposely introduced weak lateral potential energy variations
C. J. Meining, V. R. Whiteside, B. D. McCombe +4
Optically detected resonance spectroscopy has been used to investigate effects of weak random lateral potential energy fluctuations on internal transitions of charged magneto-excit…
