Molybdenum has the potential to replace graphene in the electronics industry
2023-10-26
The California Institute of Nanotechnology (CNSI) successfully used MoS2 (molybdenum disulfide) to manufacture molybdenum-based flexible micro-processing chips. This MoS2-based micro-chip is only 20% of the size of the same silicon-based chip and has extremely low power consumption. The power consumption of transistors made of molybdenum is one hundred thousandth of that of silicon transistors in standby condition, and is cheaper than graphene circuits of the same size. The biggest change is that the circuit is very flexible, extremely thin, and can be attached to human skin.
In 2011, scientists at the Swiss Federal Institute of Technology in Lausanne (EPFL) created the world's first molybdenite microchip (with smaller and more energy-efficient transistors). Mo is a strong competitor to replace silicon-based chips in the future. Professor Andras Kish, who led the research, said that molybdenum is a good next-generation semiconductor material and has broad prospects in the manufacture of ultra-small transistors, light-emitting diodes and solar cells.
Compared with silicon and graphene, one of the advantages of molybdenum is smaller volume, molybdenum monomolecular layer is two-dimensional, and silicon is a three-dimensional material. On a 0.65 nm thick molybdenum film, the movement of electrons is as easy as on a two nm thick silicon film, and molybdenite can be processed to a thickness of only three atoms!
The mechanical properties of molybdenum also make it interesting as a possible material for use in flexible electronic devices, such as flexible thin-layer wafers. It can be used to make a rollable computer or a device that can be attached to the skin. It can even be implanted in the human body.

For the first time, China has obtained kilograms of molybdenum isotopes, breaking import dependence.
Every AI news, on October 26, according to the news of CNNC, recently, the Nuclear Physics and Chemistry Institute/Company of CNNC obtained the molybdenum -100 isotope with 99% kilogram abundance for the first time through independent research and development. This is the first major breakthrough in China's autonomous supply of key molybdenum isotope materials, changing the long-standing situation that molybdenum isotopes are completely dependent on imports, and marking that China has reached the world's leading level in the field of high abundance stable isotope research, become one of the few countries in the world that can obtain molybdenum isotopes in bulk.
