“…͓DOI: 10.1063/1.2965122͔ Self-organization of metal nanoparticles, ceramic nanoislands, and semiconductor quantum dots ͑QDs͒ at surfaces is a phenomenon of relevance in materials science. [1][2][3] The attention received by these systems of nanostructures stems both from the inspiring findings related to the selfassembly process itself and from their tremendous technological potential. 4,5 While the display of appealing physical and chemical properties originally triggered the investigation of QDs, it is now equally important for the development of several QDs-based nanoelectronic, optoelectronic, and nanolithography applications to acquire the capability of fast, parallel fabrication of high-density arrays of laterally ordered nanoislands.…”

We explore the use of the pair distribution function to study the self-organization process of Ge quantum dots on both nanopatterned and nonpatterned oxidized Si(001) surfaces. Dots formation and ordering upon annealing of a Ge thin film are analyzed. The method we use is not limited to this case study. We show how it can be applied to determine short and long range self-ordering of nanostructures. We support our results by applying a software routine to simulate patterns of dots to finally spot the relevant physical aspects of Ge islands self-assembly

“…0D metal oxide nanostructures have to be synthesized under confined conditions, i.e., within the branches of dendrimers, from reverse surfactant micelles and capping agents, or within the pores of hard templates such as zeolites. Besides the confined synthesis of 0D nanoparticles, there is a surface patterning technique, in which the nanoisland arrays can be created on the substrates relying on utilizing the Asaro-Tiller-Grinfeld (ATG) instability [42,43]. Owing to their high surface energy, the 0D nanomaterials are usually highly active and thermodynamically unstable, which makes them easily grow larger or aggregate into big particles.…”

There has been exponential growth in research activities on nanomaterials and nanotechnology for applications in emerging technologies and sustainable energy in the past decade. The properties of nanomaterials have been found to vary in terms of their shapes, sizes, and number of nanoscale dimensions, which have also further boosted the performance of nanomaterial-based electronic, catalytic, and sustainable energy conversion and storage devices. This reveals the importance and, indeed, the linchpin role of nanomaterial synthesis for current nanotechnology and high-performance functional devices. In this review, we provide an overview of the synthesis strategies for designing metal oxide nanomaterials in zerodimensional (0D), one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D) forms, particularly of the selected typical metal oxides TiO2, SnO2 and ZnO. The pros and cons of the typical synthetic methods and experimental protocols are reviewed and outlined. This comprehensive review gives a broad overview of the synthetic strategies for designing "property-on-demand" metal oxide nanostructures to further advance current nanoscience and nanotechnology.

“…Recent reports of formation of self-assembled arrays of nanostructures (Rauscher et al, 2008;Ansari et al, 2013) surrounding rare earth dopant sources on the surface of YSZ marks a new paradigm in surface patterning. The dopant sources can be put in the form of thin film or lithographically patterned patches or even in the form of powder.…”
