Graphene is the best electrical conductor and also good at conducting
electricity and if it is applied to other interesting combinations of 2D
materials, the technique we used may lead to new emergent phenomena, such as
magnetism, superconductivity. The unusual electronic properties of graphene are
a two-dimensional (2D) material that is comprised of hexagonal-bonded carbon
atoms. Graphene is the strongest, thinnest material known to exist. It also a
superior conductor of electricity and has the unique atomic arrangement of the
carbon atoms in graphene. But the quality of graphene helps in turning off the
transmission of electrons through the material without altering or any changes.
The research in graphene to
create such a band gap has degraded the intrinsically good properties of
graphene, rendering it much less useful. And when graphene is compressed
between layers of Boron
Nitride (BN), an atomically-thin
electrical insulator, and the two materials are rotationally aligned, the BN
has been shown to modify the electronic structure of the graphene, creating a
band gap that allows the material to behave as a semiconductor both as an
electrical conductor and also as an insulator.
The band gap created by this type
of layering alone, but it is not large enough to be useful in the operation of
electrical transistor devices. By compressing the layers of the BN-graphene
structure, researchers found that applying pressure substantially increased the
size of the band gap and more effectively helps in blocking the flow of
electricity through the graphene. Transistors are ubiquitous in our modern
electronic devices and use graphene as a transistor it would have widespread
applications.
If you have the latest updates
and innovations in the field of Material
Science and Nanotechnology join us at
our upcoming annual congress. It’s a great opportunity to network with the
world’s leading Scientists Chemistry Research Professors. The theme of the
conference is “Using Novel Materials
Exploring Different Crystallography Techniques”. Keynote sessions by the
world’s prominent professionals and oral presentations and poster sessions on a
wide range of Material Science and Nanotechnology research.
