Examples of the high temperature applications include turbine engine control in aerospace and electronics or sensors used for drilling operation in oil and gas industry. Although traditional cooling systems can help electronics function at high temperatures, in some applications, cooling may not be possible—or it may be more appealing for the electronics to operate hot to improve system reliability or reduce cost. However, the availability of transistors and circuits for high temperature operation is very limited. https://phys.org/news/2015-02-molybdenum-disulfide-application-thin-film-transistors.html Condensed Matter Tue, 10 Feb 2015 11:00:05 EST news342785664 Move over, graphene.

That is, if we want to see miniaturization of computer components to continue. For several years, graphene has been seen as the most likely heir to the throne because it’s only one atom thick, which seems to be the physical limit for non-quamtum based computers. The problem with graphene though, is that it’s not a semiconductor in its natural state; it has to be put through special processes to make it so. Molybdenite (MoS2), on the other hand is a true semiconductor and it, like graphene can be produced in atom thick sizes, perhaps making it the ideal material to replace silicon once it reaches its size limits. Andras Kis and his colleagues at the Swiss Federal Institute of Technology in Lausanne, seem to believe so, their research into a way to create an actual integrated logic circuit from this material has been published in Nature Nanotechnology. https://phys.org/news/2012-02-molybdenite-logic-circuits-graphene.html Nanomaterials Wed, 01 Feb 2012 15:00:04 EST news247326130 (PhysOrg.com) -- Molybdenite, a new and very promising material, can surpass the physical limits of silicon.
