Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method for a nano-fine structure capable of simplifying a manufacturing step because a vacuum step and a photolithography step are unnecessary.SOLUTION: A manufacturing method for a nano-fine structure comprises the steps of: preparing a substrate; forming a plurality of nano spheres on the substrate; forming an etched film between the substrate and each nano sphere; removing each nano sphere; forming a resist layer on the etched film; forming a plurality of bumps on a surface of the substrate by removing the etched film and a part of a substrate material under the etched film by performing wet etching; and exposing each bump by removing the resist layer.
Abstract:
The present disclosure generally relates to techniques for controlled quantum dot growth as well as a quantum dot structures. In some examples, a method is described that includes one or more of providing a substrate, forming a defect on the substrate, depositing a layer on the substrate and forming quantum dots along the defect.
Abstract:
PROBLEM TO BE SOLVED: To provide a fullerene which maintains a large surface area based on a complex geometry and has a form advantageous for dispersion and high density filling.SOLUTION: The fullerene crystal forms a structure having multiple-whisker-like structures radially elongated or forms a fractal structure formed by the radial elongation of multiple-whisker-like structures and by branching of the each whisker-like structure. The fullerene crystal is obtained by adding a second solvent having a fullerene dissolution capacity lower than that of a first solvent and having a boiling point higher than that of the first solvent to a solution obtained by dissolving a fullerene in the first solvent, in a range not to precipitate (deposit) the fullerene, from the resultant solution, and the first solvent and the second solvent are vaporized to deposit crystals in order to obtain the fullerene crystal.
