Electronic gadgets along with the circuits are getting smaller by the day. Recently, a study conducted by McGill University and Sandia National Laboratories resulted in the development of the world's smallest electronic circuit.
Interestingly, the new circuit is a little higher in stage than the atomic level. The smallest circuit to date consists of two wires and is regarded as the future of the smaller electronic industry.
The most special feature of this circuit is that the two wires are separated by a distance of 15nm. The 15nm distance is the primary parameter that carries out a phenomenon called "Coulomb Drag."
The study proves that when these two wires are in their respective positions, undisturbed, the behaviour of both are different than normal. The current starts flowing inside them but in adverse directions.
The ramification of this action is that when current flows in one of the wires it is considered positive; the current flow of the other wire is negative as it flows in the adverse direction; as a result, it eventually cancels the effect, as reported by Crazy Engineers Voice.
And this is how the smallest electronic circuit functions. This innovation was part of research conducted by Guillaume Gervais from McGill's Physics Department and Mike Lilly from Sandia National Laboratories.
