Abstract: The inventive method for forming nano-dimensional clusters consists in introducing a solution containing a cluster-forming material into nano-pores of natural or artificial origin contained in a substrate material and in subsequently exposing said solution to a laser radiation pulse in such a way that a low-temperature plasma producing a gaseous medium in the domain of the existence thereof, wherein a cluster material is returned to a pure material by the crystallization thereof on a liquid substrate while the plasma is cooling, occurs, thereby forming mono-crystal quantum dots spliced with the substrate material. Said method makes it possible to form two- or three-dimensional cluster lattices and clusters spliced with each other from different materials. The invention also makes it possible to produce wires from different materials in the substrate nano-cavities and the quantum dots from the solution micro-drops distributed through an organic material applied to a glass.

Abstract: A ZnO asperity-covered carbon nanotube (CNT) device has been provided, along with a corresponding fabrication method. The method comprises: forming a substrate; growing CNTs from the substrate; conformally coating the CNTs with ZnO; annealing the ZnO-coated CNTs; and, forming ZnO asperities on the surface of the CNTs in response to the annealing. In one aspect, the ZnO asperities have a density in the range of about 100 to 1000 ZnO asperities per CNT. The density is dependent upon the deposited ZnO film thickness and annealing parameters. The CNTs are conformally coating with ZnO using a sputtering, chemical vapor deposition (CVD), spin-on, or atomic layer deposition (ALD). For example, an ALD process can be to deposit a layer of ZnO over the CNTs having a thickness in the range of 1.2 to 200 nanometers (nm).
