Molybdenum Disulfide Is One of the Ideal Materials for Transistors and Chips

Molybdenum disulfide (MoS2) is considered to be the most promising alternative to silicon due to its unique single-layer atomic structure and excellent photoelectric properties, and becomes one of the ideal materials for future applications in high-precision technology fields such as semiconductors, transistors, and chips. Therefore, in recent years, scientists have maintained a strong interest in the exploration and research of molybdenum disulfide.

Recently, the EPFL research team used molybdenum disulfide to develop a new type of "brain-like neuron transmission" computer chip, which has the ability to process and store information in the same circuit, and realize small size for computer equipment. It provides new ideas for optimization, high efficiency and energy saving.

Molybdenum disulfide is a transition metal chalcogenide two-dimensional material (TMDC). It has a graphene-like layered structure and has the characteristics of a direct band gap semiconductor that graphene does not have. Molybdenum disulfide is composed of three atomic plane layers (S-Mo-S) stacked. It has a large specific surface area, high electron migration rate, anti-magnetic resistance to radiation, low energy consumption, environmental protection, energy saving and efficiency, and high stability. And can achieve large-scale production, is an ideal material for optical and electronic equipment.

For the first time, EPFL researchers have successfully applied the two-dimensional material molybdenum disulfide to a chip that integrates data storage and logic operations. This will subvert the traditional computer model of processing data by the central processing unit (CPU) and then transmitting it to the hard disk for storage. 

According to reports, the new chips are based on floating gate field effect transistors (FGFETs) and are usually used in flash memory systems for cameras, mobile phones or computer equipment. These transistors can hold charge for a long time, and molybdenum disulfide with a thickness of only three atomic layers can not only further reduce the volume of electronic devices, but also has a strong sensitivity to the charge stored in the transistor, so logic operations can be implemented as well as data storage function.

Chinatungsten Online's molybdenum disulfide not only has great application potential in optical and electronic fields such as semiconductors and nano-transistors, but also can be used as lubricants, antioxidants, catalysts, etc., and is widely used in aviation, automobiles, mining, shipbuilding, bearings and other industrial fields.
