Systems, apparatuses, and/or methods to manufacture and/or implement a sensor film, a composite electrode, and/or a computing device such as a flexible device. The sensor film may include a random network of metal lines and graphene interconnecting the metal lines.

Thin film plasmonic optical modulator

A plasmon-based optical modulator comprises a substrate, a layer of high reflectivity material disposed over the substrate, a relatively thin dielectric layer disposed over a top major surface of the layer of high reflectivity material and a plurality of graphene strips disposed in parallel across a top major surface of the relatively thin dielectric layer, each graphene strip exhibiting a predetermined width w, with adjacent strips separated by a predetermined spacing s. A first electrical contact is coupled to the plurality of graphene strips and a second electrical contact is coupled to the layer of high reflectivity material, where the values of w, s, and voltage applied between the first and second electrical contacts determines a resonant wavelength of the plasmon-based optical modulator, with changes in the applied voltage changing between absorption and non-absorption of an applied optical input signal..

Growth graphene

The present invention provides a growth method of grapheme, which at least comprises the following steps: s1: providing an insulating substrate, placing the insulating substrate in a growth chamber; s2: heating the insulating substrate to a preset temperature, and introducing a gas containing catalytic element into the growth chamber; s3: feeding carbon source into the growth chamber and growing a graphene thin film on the insulating substrate. The present invention adopts a catalytic manner of introducing catalytic element, and rapid grows a high quality graphene on the insulating substrate, which avoids the transition process of the graphene, enables to improve the production yield of the graphene, reduces the growth cost of the graphene, and thus the mass production can be facilitated.

Spacecraft structures incorporating graphene and operation thereof

Functional components of spacecraft structures can be subject to detrimental impacts by energetic particles produced from an electric propulsion system. A graphene coating applied to a functional component can maintain electrical conductivity upon a surface of the functional component, thereby allowing charge dissipation to take place, while also resisting sputtering erosion resulting from impacts of the energetic particles.
