Chen, an assistant professor of physics, said. The researchers said that they can control the growth of this ordered array, and at the same time, this is the first time to show the electronic characteristics of individual grain boundaries-they found that the edges of single hexagonal grains in the graphene atomic lattice have clear Parallel directions, so that the direction of each crystal can be further found. The researchers used chemical vapor deposition to grow hexagonal single crystals from graphene “seeds” on copper foil in a gas chamber containing methane.
’We hope the industry will notice these new discoveries and consider ordered arrays as a possible method of manufacturing electronic components. Conversely, using a more regular ordered array can make the position of each crystal more predictable. The single crystal grain array will eliminate such problems. ’From the viewpoint of high-quality mass production achieved by silicon crystals, graphene is not yet in place, but the progress of this research can be said to be a very important step on the road to this development direction. Eric Stach, a researcher at Brookhaven National Laboratory in the United States, said he was a professor of materials engineering at Purdue University..
The new research results confirm a theory that when one grain touches graphite electrode for arc furnace another, the flow of electrons will be blocked. Qingkai Yu was the first to use this research method as a researcher at the University of Houston.’ Currently graphene is manufactured on polycrystalline plates, but this polycrystalline plate is made by random Placed and irregularly shaped ’grains’ combined together.Xin Luxun: Researchers at Purdue University in the United States have developed a manufacturing method that can improve the graphene single crystal array to achieve a method and quality similar to that of silicon crystal production.
He is now one of the corresponding authors of this research project and an assistant professor at the Ingram School of Engineering at Texas State University.’ Purdue University Nanoscience and Technology Yong P. ’Using these seeds, we can grow thousands of very regular graphene single crystal arrays,’ Qingkai Yu said.
