Graphene is a layered material composed of carbon atoms arranged in a hexagonal pattern. It has found use in industry and science. It is an amazing material that could change the world with its properties. It has excellent conductivity in various forms. It can be used in various medicine-...
James Tour, a chemistry professor at Rice University, says that this is “certainly the easiest method I’ve seen for making [graphene thin films] over large areas.” He thinks that the process could easily be converted into a larger, commercial-scale manufacturing technique. “It’s very ame...
For many applications in electronics and energy technology, however, graphene must be combined with other materials: Since graphene is so thin, its properties drastically change when other materials are brought into direct contact with it. However, combining graphene with other materials at the molecul...
Ultrathin carbon is a strong electrical and thermal conductor, making it ideal for enhancing semiconductor chips in electrical devices.
However, this traditional view doesn’t fully explain the behavior of electrons in certain emerging quantum materials, such as graphene — a highly conductive, ultrathin material. In graphene, electrons don’t move independently but instead flow collectively, resembling the movement of a viscous fluid...
(ii) cooling the thin metal film to strip the carbon out of it because of the decrease in solubility, and (iii) the surface generation of graphene layers. Another method, called plasma-enhanced chemical vapor deposition (PECVD), has advantages compared to CVD, such as direct growth on ...
Efficient spin generation and manipulation require a large spin-orbit coupling (SOC), with GaAs a prototypical system, whereas long spin lifetimes (τs) is mostly found in weak SOC materials, such as graphene and diamond. Materials with large SOC as well as long τs are ideal for spintronic...
Graphene consists only of carbon atoms, but magnetism is a property hardly associated with carbon. So how is it possible for carbon nanomaterials to exhibit magnetism? To un-derstand this, we need to take a trip into the world of chemistry and atomic physics. ...
