Graphene gains new properties of thermal sensitivity or changes the way people work and play
For four years, two scientists in the United States have been trying to modify the graphene so that it has thermal sensitivity for use in infrared imaging equipment. Currently, they have successfully developed new materials with magnetic, optical, electrical, and thermal properties that can be widely used in military goggles, cell phone cameras, photodetectors, and transistors, and are expected to change the way people work and play. Graphene is a material that is 1 million times thinner than hair. It is composed of carbon atoms arranged in a honeycomb structure and has superior electrical conductivity, durability, and plasticity. Northeastern University physicists Swasdiko Kar and Srinivas Sridar have been hoping to develop new materials that have properties beyond graphene by adding other elements to graphene. According to a recent report by the Physicist Organization Network, at the beginning of the study, the Karl team added boron and nitrogen to graphene, but spent a lot of time trying to remove the oxygen that was mixed into the product because they were concerned that oxygen would contaminate this developing "Pure" material. But then they realized that they couldn't ignore the important role of oxygen in it and decided to use the best way to control the oxygen. The results show that after the addition of oxygen, the behavior of the new material in the reaction chamber is completely beyond their imagination: oxygen determines the mixing of other elements such as boron, carbon, and nitrogen in solid crystals. Carl explained that a small amount of oxygen “etched away†some of the carbon, freeing up space for the addition of boron and nitrogen, “as if oxygen controls the geometry of the new material.†They named the new substance “2D-BNCO,†which means that it consists of four elements: boron, nitrogen, carbon, and oxygen, and it is a two-dimensional ultra-lightweight material. Researchers used electron microscopy and spectroscopic tools to analyze new materials. The results showed that they possess magnetic, electrical, and optical properties, as well as the thermal properties of the US Department of Defense Advanced Research Projects Agency (DARPA). The potential applications of new materials are very broad: from 20-megapixel arrays for cell phones to photodetectors to atomic-thickness transistors. Next, they will check the mechanical properties of the new material and confirm its magnetic properties with experiments. It is reported that the US military research laboratory and DARPA provided funding for this research.
