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.

The effect of a charge trap in the vicinity of the quantum-dot on the charge stability diagram of a single electron transistor [PDF]
AUT Journal of Electrical EngineeringIn this article, we explored the effect of a single charge trap on the charge stability diagram of the quantum-dot-based single-electron transistor. We investigated anomalies in the coulomb characteristic diagram, system energy, occupation probabilities,

15.13% Sr-doped CsPbI3 quantum dots with near-unity quantum yield via surface ligand compensation
Nano ResearchSr-doping of perovskite quantum dots (QDs) is a promising strategy to reduce Pb content and improve optical performance and stability. However, excessive Sr introduces new defects that degrade photoluminescence quantum yield (PLQY).

Formation InAs Quantum Dots in a Matrix GaAs in Kinetic Mode for CVD-method [PDF]
Журнал нано- та електронної фізики, 2017 We present the results of theoretical study for the kinetic mode of quantum dot formation in the InAs / GaAs system. The theory is valid at the kinetic stage of quantum dot formation, when the island ensemble remains dilute and thus noninteracting.
