As a typical material with two dimensions, graphene is widely used and highly desired in the scientific and industrial community. What exactly is a 2-dimensional material? Simple, two-dimensional material is a non-nanoscale (1 to 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 and others.

2D materials can be used in a variety of fields. For example, spintronics and printed electronics are two examples. , 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 three atoms of thickness. The graphene thickness is nearly the same as molybdenum, but graphene has no band gap. In this context, the author has previously revealed that the US Department of Energy Berkeley Lab’s research team accurately measured band gap of the two-dimensional semiconductor material molybdenum-disulfide.

In addition, the molybdenum diulfide has an electron mobility that is 100 cm2 /vs. (ie. 100 electrons per centimeter square per volt) although it is much lower 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.
