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…
