Molybdenum Disulphide (MoS2) has been used in ancient Egypt since 5000 BC for its excellent lubricating properties. MoS2 has similar lubricating properties to lead, graphite and hexagonal boron nitride. While graphite requires water to display low friction behaviour, water is detrimental to MoS2 and for this particular reason has been used mainly in space applications for the past 50 years. MoS2 is also a diamagnetic material and a semiconductor with an indirect bandgap of 1.23 eV which make an ideal material in photonics and microelectronics application. While the properties of the bulk material are interesting, it is as single layer and thin film form that MoS2 has shown exceptional behavior, outperforming graphene in some applications. It is important to not at this stage that the deposition technology used will decide on the properties and therefore there are as many type of MoS2 as there are depositions techniques. In this presentation you will be shown how technology drive properties and what can be achieved with this wonder molecule.
