Description

[0002] Graphene is a two-dimensional crystal composed of carbon atoms that is peeled off from graphite material and is only one atom thick. It is currently the thinnest and strongest material in nature. If a piece of graphene with an area of ​​1 square meter is used to make a hammock, it weighs less than 1 mg and can support a cat weighing 1 kilogram. The most promising application of graphene at present is to become a substitute for silicon to manufacture ultra-micro transistors for the production of future supercomputers. Replacing silicon with graphene will make computer processors run hundreds of times faster. In addition, graphene is almost completely transparent and absorbs only 2.3% of light. On the other hand, it is very dense and even the smallest gas atoms (helium atoms) cannot penetrate it. These characteristics make it very suitable as a raw material for transparent electronic products, such as transparent touch screens, light panels and solar panels.
