Goodbye Silicon tradition?

Swiss scientists have made microchips from a completely new material in place of traditional silicon.

Molybdenum Disulfide MoS2 on many parameters outperforms conventional silicon and its use in electronic devices allows for a much smaller and more flexible generation of products.

A team of Swiss scientists at the Polytechnic University of Lausanne has announced that their nanoscale electronics laboratory and nanostructure have built integrated electronics in which instead of silicon materials They used molybdenum compounds.

Testing their microchips shows that the molybdenum in electronics can overcome the physical limitations of silicon materials such as size, energy consumption and mechanical ductility.

Earlier this year, his laboratory discovered that molybdenum molybdenum, MoS2, a relatively common mineral in nature called molipdenite, is an ideal semiconductor. Suitable for the manufacture of transistors. On a number of characteristics they exceed the components from silicon, but even more than parameters of materials also 'strange' is graphene.

Kis says the advantage of molybdenite is that electronic devices using components made from this material are easier to shrink than silicon components. For example, if the silicon is processed below 2 nanometers, it begins to oxidize and deteriorate significantly. While integrated circuits use molybdenum to work steadily even when the thickness is only three atoms, it can be made into much smaller chips. MoS2 transistor switches are faster than silicon transistors. Due to its mechanical properties, molybdenum is a very attractive material for use in electronic devices that require plasticity, which can be curved for example. Production of computers can be rolled up into a tube or made directly over the human skin.
