Molybdenum sulfide does away with (some) carbon nanotube problems

Abstract:
Carbon nanotubes are discussed as a future alternative to silicon-based transistors, but some material properties have turned out as an obstacle to industrial implementations. Now Danish and German researchers came up with an alternative to the alternative: Molybdenum sulfide has similar properties as carbon nanotubes — minus its drawbacks.

Carbon nanotubes are on the agenda of many researchers since they feature excellent semiconducting properties. For this reason, technologists hope to be able to replace silicon transistors and memories in the long run by carbon nanotubes. However, drawbacks such as their tendency to stick together hitherto have prevented their industrial breakthrough. Besides sticking together, it is extremely difficult to apply electric contacts to them.

Researchers from the Univerity of Aarhus (Denmark), the Dresden Technical University and the Rossendorf Research Center (FZD) have been able to characterize molybdenum sulfide. The results which have been achieved both by experiments as well as by quantum mechanical simulation showed that the material which in the macro world is used as a lubricant in nano dimensions exposes very interesting properties from the perspective of semiconductor technology: Molybdenum sulfide nano particles for wires. When twisted, the wires turn conductivity on or off, thus they could be used as electric nano switches.
