In contrast to graphene, 2D- MoSeĢ has a direct band gap, suggesting applications in transistors and photodetectors. Ģ is significantly higher than that of 2D- MoSĢ adopts structures reminiscent of graphene, although the latter's electron mobility is thousands of times greater still. The synthesis reaction of MoSeĢ are produced by scotch tape exfoliation from bulk crystals or by chemical vapor deposition (CVD). Excess selenium can be removed by sublimation under vacuum. Stoichiometric layers crystallize in a hexagonal structure as the sample cools. It has to be heated very gradually to prevent explosion due to its strong exothermic reaction. Chemical vapor transport with a halogen (usually bromine or iodine) is used to purify the compound at very low pressure (less than 10-6 torr) and very high temperature (600–700 ☌). Synthesis Ģ involves direct reaction of molybdenum and selenium in a sealed tube at high temperature. The coordination geometry of the Mo is sometimes found as octahedral and trigonal prismatic. The metal ion in these compounds is surrounded by six Se 2− The most common form of these TMDCs have trilayers of molybdenum sandwiched between selenium ions causing a trigonal prismatic metal bonding coordination, but it is octahedral when the compound is exfoliated. These interactions lead to exfoliation into two-dimensional layers of single unit cell thickness. Structure Ģ is a layered material with strong in-plane bonding and weak out-of-plane interactions. Compared to MoSĢ exhibits higher electrical conductivity. These compounds, as the name suggests, are made up of a transition metals and elements of group 16 on the periodic table of the elements. Compounds of this category are known as transition metal dichalcogenides, abbreviated TMDCs. Its structure is similar to that of MoSĢ. 2) is an inorganic compound of molybdenum and selenium.
