Graphene, which is an example of a two-dimensional materials, has been used extensively in many areas and is sought after by scientists and the industrial sector. Now, let’s clarify what two-dimensional materials are. A two-dimensional material refers to materials where electrons can move freely (planarmotion) on non–nanoscale (1 – 100 nm) in both dimensions. These materials include: graphene; boron nutride; transition metal compounds, (disulfide); Molybdenum; tungsten-disulfide; tungsten-disilicide; black phosphorus and others.
2D materials offer many potential applications. Combining all the information from previous authors, you can see the following: spintronics. , quantum dots, sensors, semiconductor manufacturing, NFC, medical, etc.
Molybdenum Disulfide (MoS2) – a type of two-dimensional materials – is also worth attention. Molybdenum dioxide is composed of both a molybdenum, as well as a sulfur atom. This material has an atomic thickness of just three. This is very similar to graphene. But molybdenum-disulfide’s band gap at 1.8 eV is much larger than graphene. Here, the author once mentioned that the Berkeley Lab of the US Department of Energy measured the semiconductor band gap of Molybdenum Disulfide (MoS2). They also discovered an effective The tuning mechanism.
The electron mobility of molybdenum-dioxide is about 100 cm 2/vs. That’s 100 electrons per square millimeter per voltage, but it’s still much higher than that of the crystal. It has an electron transfer of 1400cm2/vs but a greater migration rate that amorphous and ultra-thin silicon.
Molybdenum dioxide is an excellent choice for application in transistors. Flexible electronics, LEDs. lasers. Solar cells.
