Theory of polaron resonance in quantum dots and quantum-dot molecules [PDF]
Journal of Applied Physics, 2007 This work presents the theory of exciton coupling to photons and longitudinal optical (LO) phonons in quantum dots (QDs) and quantum-dot molecules (QDMs). Resonant-round trips of the exciton between the ground (bright) and excited (dark or bright) states, mediated by the LO phonon, alter the decay time and yield the Rabi oscillation.

Designing quantum dots for solotronics [PDF]
Nature Communications, 2014 AbstractSolotronics, optoelectronics based on solitary dopants, is an emerging field of research and technology reaching the ultimate limit of miniaturization. It aims at exploiting quantum properties of individual ions or defects embedded in a semiconductor matrix. It has already been shown that optical control of a magnetic ion spin is feasible using

Growth and Characterization of Quantum Dots and Quantum Dots Devices [PDF]
, 2003 Quantum dot nanostructures were investigated experimentally and theoretically for potential applications for optoelectronic devices. We have developed the foundation to produce state-of-the-art compound semiconductor nanostructures in a variety of materials: In(AsSb) on GaAs, GaSb on GaAs, and In(AsSb) on GaSb. These materials cover a range of energies
