According to the report of the Physicist Organization Network on September 5, American scientists discovered that the use of gold atoms to manipulate three atoms of molybdenum disulfide (MoS2) can significantly improve the electrical properties of molybdenum disulfide. Recent research has helped scientists develop high-performance ultrathin electronic devices and plasma devices. The study was published in the latest issue of Nano Express. Molybdenum disulfide has some remarkable properties like single-atom-thick "magic material" graphene, but graphene lacks bandgap, which means that devices made of graphene can only be opened and cannot be closed, so they cannot be used. To make digital logic; and molybdenum disulfide has a band gap, and therefore is expected to join with graphene as a new two-dimensional platform for electronic devices. A team of researchers led by Professor of the Department of Chemical Engineering at Kansas State University studied the structure of molybdenum disulfide and found that the surface of the material sulfur group will have a strong chemical reaction with precious metals including gold. By creating a bond between molybdenum disulfide and gold nanostructures, they discovered that this key acts like a highly coupled gate capacitor. Berry explained: "The spontaneous, high-capacitance, lattice-driven interface possessed by the precious metal on the surface of the metal disulfide layer can be used to coordinate the carrier concentration, transport barriers, and phonon transport of future devices. Happening." The research team plans to create more complex nanostructures on molybdenum disulfide to make logic devices and sensors. They said: "The integration of gold into molybdenum disulfide provides a new method for manufacturing transistors, biochemical sensors, plasma equipment, and catalyst susceptors." The latest research is expected to promote the performance of devices such as transistors, sensors, and thermal coatings. Enhancing; can also encourage scientists to develop ultra-fast, ultra-thin logic devices and plasma equipment. Berry's laboratory is leading the world in the synthesis and analysis of next generation atomic-thickness nanomaterials (such as graphene and boron nitride layers) that have been widely used to make sensitive detectors. , electronic equipment, rugged composite materials and novel biological nanodevices. Berry said: "The structure of these atomic thicknesses is expected to be used to make electronic devices that are only a few atoms thick, thus thoroughly revolutionizing the appearance of electronic devices."
