 Molybdensdisulfid can provide smaller and more energy efficient than silicon transistors. The claim Swiss researchers. Now they have made the first chip.
Minerals molybdensdisulfid, MoS 2, can challenge both silicon and
graphene in electronics manufacturing in the future. It claimed a group
of researchers at the EPFL, Ecole Polytechnique Federale de Lausanne,
in the early years of a scientific paper in Nature Nanotechnology.
Now the group has built the first test chips in the material, also
called molybdenit molybdenum or shine. The chips have only two to six
transistors each, but scientists say they can produce larger chips.
The main advantage of molybdenum disulfide is that it allows us to
reduce the size of transistors, says Prof. Andras Kis in a statement.
The reason is that molybdensdisulfid is useful even in very thin layers,
only three atomic layers thick. This makes it possible to produce
transistors that are significantly smaller than current silicon
versions. Power can also be turned off quickly and the transistor draws
considerably less power in idle compared to silicon transistors.
The Nobel Prize material graphene is another contender for silicon in
future electronics. But according to Swiss researchers have molybdenum
one important advantage: the material is much better at strengthening
electrical signals.
Molybdenum Gloss is currently used as an additive in steel and
lubricants. But its properties as semiconductors have not been
investigated thoroughly before. Much research remains before we can
expect to see commercial MoS 2-circuits.
The Swiss researchers describe the new test circuits in the journal ACS Nano. Read: The scientific article in ACS Nano
