As a typical, two-dimensional material graphene finds wide application in many fields. It is also highly sought after both by industry and the scientific community. What exactly is a 2-dimensional material? Simple, two-dimensional material is a non-nanoscale (between 1 and 100 nm) material in which electrons are able to move freely in two directions (planar movement). Examples of such materials include: graphene; boron nitride; transition metal compounds (disulfide); Molybdenum; tungsten diulfide; tungsten diilicide; black phosphorus.
2D materials can be used in a variety of fields. Examples of 2D materials include spintronics, printed electronics, flexible electronics, microelectronics, memory, processors, hyperlenses, terahertz, supercapacitors, solar cells, security labels. , quantum dots, sensors, semiconductor manufacturing, NFC, medical, etc.


Molybdenum diulfide, also known as MoS2, is a two-dimensional material that deserves our attention. Molybdenum diulfide, which is composed of two atoms of molybdenum with one atom of sulfur, has only a three-atom thickness. The graphene thickness is nearly the same as molybdenum, but graphene has no band gap. The author of the article has previously stated that the US Department of Energy Berkeley Lab research team accurately measured band gap of semiconductor two-dimensional molybdenum-disulfide material (MoS2). They have also revealed powerful The tuning mechanisms and relationship between electronic and optical properties of 2D material.


In addition, the molybdenum diulfide has an electron mobility that is 100 cm2 /vs. (ie. 100 electrons per centimeter square per volt), although it's much lower than crystal. The silicon has an electron migration rate of about 1400 cm2/vs. However, it is better than amorphous silica and other ultra thin semiconductors.

Molybdenum diulfide, with its excellent semiconductor characteristics and small size and ultra-thinness, is ideal for use in flexible electronics, solar cells, LEDs and lasers.
