Researchers from technology giant IBM, have recently managed to build a complete Graphene circuit on a single Silicon Carbide wafer.Recently reported in a paper published by the journal ‘Science’, they have shown that it is feasible to implement a monolithic integration of Graphene. This is the first time that monolithic integration of Graphene has been achieved and is seen by many as a significant achievement.
So What Exactly is Graphene?
Graphene is essentially a one atom thick planar sheet of Carbon atoms arranged in a honeycomb like lattice. The structure of Graphene was originally described by Hanns-Peter Boehm in 1962. Multiple layers of Graphene take the form of the better known ‘Graphite’ that we all find in our pencils.
The Graphene Circuit
The circuit that the researchers have produced is a fully functioning broadband radio frequency mixer which can operate up to 10 GHz (Ten Billion times per second). This type of mixer is often used in common electronic applications such as TV, Radio, Mobile phones , Satellites etc.
