Molybdenum may replace graphene in electronic industry
The California Institute of Nanotechnology (CNSI) has successfully used MoS2 (molybdenite, molybdenum disulfide) to manufacture molybdenite based flexible microchips. This MoS2 based microchip is only 20% of the size of silicon-based microchips, and its power consumption is extremely low. The power consumption of Molybdenite based transistors in standby mode is one thousandth of that of silicon-based transistors, And it's cheaper than graphene circuits of the same size. The biggest change is that the circuit is very flexible, very thin, and can be attached to the human skin.
In 2011, EPFL scientists produced the world's first molybdenite microchip with smaller and more energy-efficient transistors. Molybdenite is a strong competitor to replace silicon-based chips in the future. Professor Andras Kish, who led the research, said that molybdenite is a good next-generation semiconductor material and has broad prospects in manufacturing ultra small transistors, light-emitting diodes and solar cells.
Compared with silicon and graphene, one of the advantages of molybdenite is its smaller volume. Molybdenite monolayer is two-dimensional, while silicon is a three-dimensional material. On a 0.65 nm thick molybdenite film, electron motion is as easy as on two nm thick silicon film. Molybdenite can be processed to only three atoms thick!
Molybdenite has attracted much attention due to its mechanical properties. It may be used as a material in elastic electronic devices, such as elastic thin-layer wafers. It can be used to make curly computers or devices that can be attached to the skin. It can even be implanted into the human body.
The British journal Nature Nanotechnology pointed out: monolayer molybdenite materials show good semiconductor properties, some of which are better than silicon and graphene, which are widely used now, and are expected to become the next generation of semiconductor materials.

The application of molybdenum in other alloys and chemical industry is also expanding. For example, molybdenum disulfide lubricant is widely used in all kinds of machinery lubrication, molybdenum metal is gradually used in nuclear power, new energy and other fields. Due to the importance of molybdenum, governments all over the world regard it as a strategic metal. Molybdenum was widely used in manufacturing weapons and equipment at the beginning of the 20th century. Modern high-precision and sophisticated equipment has higher requirements for materials, such as molybdenum and tungsten, chromium and vanadium alloys used in manufacturing alloy components and parts of warships, rockets and satellites.
Molybdenum is widely used as substrate of different film surfaces in thin film solar energy and other coating industries.
