Molybdenum disulfide (MoS2) is considered the most promising alternative to silicon because of its unique monolayer atomic structure and excellent optoelectronic properties and becomes one of the ideal materials for future applications in semiconductor, transistors, chips, and other advanced science and technology fields. Therefore, in recent years, scientists have maintained a strong interest in the exploration and research of molybdenum disulfide (MoS2).
Recently, the EPFL research team used molybdenum disulfide (MoS2) to develop a new type of “brain-like neuron transmission” computer chip that has the ability to process and store information in the same circuit. This provides new ideas for miniaturization, high efficiency, and energy-saving of computer equipment.
Molybdenum disulfide is a transition metal chalcogenide two-dimensional material (TMDC), with a graphene-like layered structure, and has the characteristics of a direct bandgap semiconductor that graphene does not have.
The 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 and radiation resistance, low energy consumption, environmental protection, energy-saving and efficiency, and high stability. Moreover, it can realize large-scale production and 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 transferring it to the hard disk for storage. Related results are published on “Nature”.
According to reports, the new chips are based on floating gate field-effect transistors (FGFETs) and are usually used in flash memory systems in cameras, mobile phones, or computer equipment. These transistors can hold the 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. Therefore, logic operations and data storage functions can be realized at the same time.
Molybdenum disulfide has great application potential not only in semiconductors, nano-transistors, and other optical electronics fields. At the same time, it can also be used as a lubricant, antioxidant, catalyst, etc., and is widely used in aviation, automotive, mining, shipbuilding, bearings, and other industrial fields.
