According to a report from the Physicist Organization Network on April 16, scientists at the University of Wisconsin-Milvoku in the United States have discovered a new carbon-based material, graphene oxide (GMO), which is synthesized from the carbon family's magic material, graphene. The new semiconductor material helps carbon to replace silicon and is used in electronic devices. Graphene's electrical and thermal conductivity is extremely strong and far exceeds that of silicon and other traditional semiconductor materials. The size of transistors made of silicon is approaching the limit. Scientists believe that carbon materials at the nanometer scale may be "life-saving straws" and graphite. Alkenyl is expected to replace silicon as an electronic component material in the future. However, because it is too expensive to be mass-produced, the application of graphene is currently very limited, and graphene-related materials have so far only existed as conductors or insulators. Chen Junhong, a professor of mechanical engineering and a member of the research team, said: “One of the main drivers of graphene research is to make this material a semiconductor. We have obtained a new material, GMO, by chemical modification of graphene. The properties shown demonstrate that it is easier to produce on a large scale than graphene." When the team was researching a hybrid nanomaterial developed by Chen Junhong, he unwittingly obtained GMO. Initially, the object of their study was a hybrid nanomaterial consisting of carbon nanotubes (rolled from graphene in a cylindrical shape) with tin oxide nanoparticles on the surface. Chen Junhong used this hybrid material to produce high performance, High efficiency and cheap sensor. In order to better understand the performance of this hybrid material, scientists need to find ways to turn graphene into its “cousinâ€â€”an insulator graphene oxide (GO) that can be produced on a large scale and inexpensively. GO consists of graphene stacked in misalignment. In the experiment, Chen Junhong and professor of physics Mariga Gadadezska heated GO in a vacuum to remove oxygen. However, the carbon and oxygen atoms in the GO layer are not destroyed but become neatly arranged, becoming an ordered semiconductor GMO that does not exist in nature. Researcher Eric Mattson said: "We think that oxygen will leave, leaving behind multiple layers of graphene, but the result is not the case. Let us be surprised." Gadadzka stated that since GMO is a single-layered form, it may be licensed for use in products relating to surface catalysis. They are exploring their use in lithium-ion battery anodes and GMOs are likely to improve the performance of lithium-ion anodes. The team then needs to understand what triggered the reorganization of this material and what environment would undermine the formation of GMOs. Michael Mevner, director of the surface research laboratory at the University of Wisconsin Milwaukee, said: "The reduction reaction will remove oxygen, but in reality, we get more oxygen. Therefore, there are still many things we need to understand." Mevner pointed out that at present, they only produce GMOs on a small scale in the laboratory, and they are not sure what problems they will encounter in large-scale manufacturing.
