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.

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.

Based on DNA origami, an algorithm is proposed for Graph’s Connectivity problem via the self-assembly of DNA origami structures. The desired DNA origami structures can be constructed. These structures can encode the information of Graph’s vertices and edges, because these structures have sticky ends, so they can assemble to advanced structures representing the information of a graph via specific hybridization. Via strand displacement reaction and agarose gel electrophoresis, the vertices can be deleted and the graph’s connectivity can be tested one by one. This is a highly parallel method, and can reduce the complexity of Graph’s Connectivity problem greatly.
