Recently, “Nano Express” published a new application of laser pointer technology. Researchers from University of Jyväskylä, Finland, and Taiwan, China have discovered that laser writing technology can be used to change the two-dimensional structure of graphene carbon atoms into three dimensions. Objects, and graphene’s three-dimensional structured substance have strong stability, showing different electrical and optical characteristics from two-dimensional structure.
As we all know, graphene can be used to make a variety of electronic and optoelectronic devices. Some scientists predict that graphene will “completely change the 21st century”, which may set off a disruptive new technology and new industry revolution that sweeps the world. It is understood that the current graphene technology is upgraded by laser writing. The process application is similar to forging a metal into a three-dimensional shape using a laser beam “hammer”. Finally, through experiments and computer simulations, observe and understand the authenticity of the two-dimensional structure of graphene carbon atoms to three-dimensional shape and its formation mechanism.
In nature, the structure determines the properties. The structural characteristics of green laser pointer graphene are no exception. Graphene is thin and hard, has good light transmittance, strong thermal conductivity, high electrical conductivity, stable structure, and fast electron migration. The industry believes that graphene can be divided into single-layer graphene, double-layer graphene, few-layer graphene, and multi-layer graphene according to the number of layers in the electronic application process. Because the excellent performance of graphene will decrease significantly with the increase of the number of layers. If it exceeds multiple layers, it will not have the excellent performance of graphene materials, and will lose the advantages of graphene in the upgrade of electronic devices. This two-dimensional to three-dimensional structure upgrade opens up new application directions for graphene applications.
