Graphene, a typical material with two dimensions, is widely used and highly sought-after by scientists and the industry. 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. The following examples combine the introductions from the authors: 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 typical 2-dimensional material that deserves our attention. Molybdenum diulfide, which is composed of two atoms of molybdenum with one atom of sulfur, has only three atoms of thickness. The graphene thickness is nearly the same as molybdenum, but graphene has no band gap. The author of this article once stated that the US Department of Energy Berkeley Lab had accurately measured band gap of semiconductor two-dimensional materials molybdenum sulfide and revealed a powerful tuning mechanism.

In addition, the molybdenum diulfide has an electron mobility that is 100 cm2 /vs. (100 electrons per centimeter square per volt) – albeit much less than the 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 transistors, flexible electronic devices, LEDs, Lasers, and Solar Cells.
