AbstractWe investigated the nucleation of Ga droplets on singular GaAs(111)A substrates in the view of their use as the seeds for the self-assembled droplet epitaxial quantum dots. A small critical cluster size of 1–2 atoms characterizes the droplet nucleation. Low values of the Hopkins-Skellam index (as low as 0.35) demonstrate a high degree of a spatial order of the droplet ensemble. Around $$350\,^{\circ }\hbox {C}$$ 350 ∘ C the droplet size distribution becomes bimodal. We attribute this observation to the interplay between the local environment and the limitation to the adatom surface diffusion introduced by the Ehrlich–Schwöbel barrier at the terrace edges.

Interdigitated Array

We demonstrated electroluminescence from hybrid 1D glass fibres incorporating CdTe quantum dots with a thin SiO2 overlayer which contains CdS-like clusters. The self-organised fibres, prepared by refluxing precursor nanowires, exhibited red electroluminescence on Au interdigitated array electrodes at room temperature. Although fluctuation with time was observed in the electroluminescence, relatively low threshold electric field (2.6 × 106 V m–1) suggests that the CdTe quantum dots-based hybrid fibres are expected to be applied to low voltage driven electroluminescent devices.

Formation And Evolution

We review the concepts and principal experimental results pertaining to the self-assembly and self-ordering of quantum dots in semiconductor systems. We focus on the kinetics and thermodynamics of the formation and evolution of coherently strained 3D islands, and the effects of strain on nucleation, growth, and island shape. We also discuss ongoing research on methods to control the density, size, and size distributions of strained islands, both within a single strained layer and in quantum dot (QD) multilayers.
