ABSTRACT
We demonstrate the production of a well ordered three-dimensional array of Ge quantum dots in amorphous silica matrix. The ordering is achieved by ion beam irradiation and annealing of a multilayer film. Structural analysis shows that quantum dots nucleate along the direction of the ion beam used for irradiation, while the mutual distance of the quantum dots is determined by the diffusion properties of the multilayer material rather than the distances between traces of ions that are used for irradiation.

    We perform first-principles calculations to investigate the defect properties of O vacancies in amorphous HfSiO4. For atomic models generated from molecular dynamics simulations, we find that O vacancies, which have only Hf atoms or a mixture of Hf and Si in the neighborhood, behave as charge...

    The Coulomb blockade (CB) in quantum dots (QDs) is by now well documented. It has been used to guide the fabrication of single electron transistors. Even the most sophisticated techniques for synthesizing QDs (e.g. MOCVD/MBE) result in an assembly in which a certain amount of disorder is...

    This paper presents a study on the formation and shape control of InAsSb/InP nanostructures on InP (001) substrates. For the formation of InAsSb nanostructures, incorporation of Sb atoms into InAs islands results in significant morphology change in the islands due to the surfactant effect of Sb...

    We demonstrate that by changing the substrate temperature at which Ga droplets form and by varying the InAs deposition, we are able to control the configuration of quantum dots per GaAs mound. The size of the Ga droplets increases with increasing substrate temperature and resulting...

    Application of InGaAs/GaAsN strain-compensated superlattice (SCSL) to InAs quantum dots (QDs) has been studied with atomic force microscopy (AFM), reflection high-energy electron diffraction (RHEED), and temperature-dependent photoluminescence (PL) measurements. The insertion of a...

    A quantitative thermodynamic model has been established to investigate the evolution mechanism from quantum dot (QD) to quantum ring (QR) during the capping process. Taking the Ge/Si system as an example, we found that there is a critical concentration of Ge required in QDs in order for Si...

    The effects of spacer thickness on lateral alignment and density of InGaAs quantum dots on GaAs(311)B substrates is investigated. As the thickness of the spacer layers is increased, the two-dimensional lateral ordering previously demonstrated on GaAs(311)B is replaced by the one-dimensional dot...
