Hybridization of Electron and Hole States in Semiconductor Quantum-Dot Molecules

• A novel QD-molecule system is realized using metal–organic vapor-phase epitaxy growth. The dots are tunnel coupled via connected quantum wires (QWRs). The stronger tunnel coupling in this integrated QD-QWR system allows the hybridization of both electron and hole states, yielding direct-real-space excitonic molecules (see image). The structure holds promise for nanophotonic devices for quantum-information-processing applications.
