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…
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…
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…
Electric field induced narrowing of exciton line width
I. V. Ponomarev, L. I. Deych, A. A. Lisyansky
Considering effects of electric field on the low temperature absorption line of quantum well excitons, we show that, for moderate strength of the electric field, the main contribut…
Effect of inter-wall surface roughness correlations on optical spectra of quantum well excitons
I. V. Ponomarev, L. I. Deych, A. A. Lisyansky
We show that the correlation between morphological fluctuations of two interfaces confining a quantum well strongly suppresses a contribution of interface disorder to inhomogeneous…
