4289 results about "Crystallinity" patented technology

Crystallinity refers to the degree of structural order in a solid. In a crystal, the atoms or molecules are arranged in a regular, periodic manner. The degree of crystallinity has a big influence on hardness, density, transparency and diffusion. In a gas, the relative positions of the atoms or molecules are completely random. Amorphous materials, such as liquids and glasses, represent an intermediate case, having order over short distances (a few atomic or molecular spacings) but not over longer distances.

Fluoropolymer binders for carbon nanotube-based transparent conductive coatings

This invention relates to flexible, transparent and conductive coatings and films formed using carbon nanotubes (CNT) and, in particular, single wall carbon nanotubes, with polymer binders. Preferably, coatings and films are formed from carbon nanotubes applied to transparent substrates forming one or multiple conductive layers at nanometer level of thickness. Polymer binders are applied to the CNT network coating having an open structure to provide protection through infiltration. This provides for enhancement of properties such as moisture resistance, thermal resistance, abrasion resistance and interfacial adhesion. Polymers may be thermoplastics or thermosets, or a combination thereof. Polymers may also be insulative or inherently electrical conductive, or any combination of both. Polymers may comprise single or multiple layers as a basecoat underneath a CNT coating, or a topcoat above a CNT coating, or combination of the basecoat and the topcoat forming a sandwich structure. A fluoropolymer containing binder, which is a solution of one fluoropolymer or a blend of fluoropolymers, which may be formulated with additives, is applied onto a carbon nanotube-based transparent conductive coating at nanometer level of thickness on a clear substrate such as PET and glass. The fluoropolymers or blend can be either semi-crystalline (with low level of crystallinity) or amorphous, preferably to be amorphous with low refraction index. Binder coating thickness can be adjusted by changing binder concentration, coating speed and/or other process conditions. This binder coating significantly improves optical transparency, and also maintain or increases conductivity of the CNT-based coating. With other benefits such as abrasion, thermal and moisture resistance, this binder coating and the resulting products is used for display and electronic applications.

ß-Ga2o3 single crystal growing method, thin-film single crystal growing method, Ga2o3 light-emitting device, and its manufacturing method

A method for growing a β-Ga2O3 single crystal hardly cracking and having a weakened twinning tendency and an improved crystallinity, a method for growing a thin-film single crystal with high quality, a GazO3 light-emitting device capable of emitting a light in the ultraviolet region, and its manufacturing method are disclosed. In an infrared-heating single crystal manufacturing system, a seed crystal and polycrystalline material are rotated in mutually opposite directions and heated, and a β-Ga2O3 single crystal is grown in one direction selected from among the a-axis <100> direction, the b-axis <010> direction, and the c-axis <001> direction. A thin film of a β-Ga2O3 single crystal is formed by PLD. A laser beam is applied to a target to excite atoms constituting the target Ga atoms are released from the target by thermal and photochemical actions. The free Ga atoms are bonded to radicals in the atmosphere in the chamber. Thus, a thin film of a β-Ga2O3 single crystal is grown on a substrate of a β-Ga2O3 single crystal A light-emitting device comprises an n-type substrate produced by doping a β-Ga2O3 single crystal with an n-type dopant and a p-type layer produced by doping the β-Ga2O3 single crystal with a p-type dopant and junctioned to the top of the n-type substrate. The light-emitting device emits a light from the junction portion.
