Lossless Transmission Of High Frequency Electrical Signals Possible In Graphene
Researchers from the Plymouth University have recently discovered a new and unique property of Graphene. A study led by Dr Shakil Awan reports that when a high frequency electrical signal passes through a one atom thick graphene channel, it does not lose any energy. The “wonder material†Graphene, a symmetric carbon allotrope is already famous for its strength, electrical and thermal properties. With the help of the latest groundbreaking phenomena, the electronics industry is likely to take a step forward.
The team explained that Graphene overpowers any super conductor in terms of channeling high-frequency electrical signals without the expense of additional energy. Unlike conventional conductors, semi-conductors, and insulators, Graphene lacks a band gap as conduction and valence bands meet at the Dirac points. Owing to such a peculiar structure, Graphene is the most suitable choice for a range of next-generation electrical amplifiers and bio-sensors.
Motivated by its application in dementia detecting bio-sensors, scientists had chosen graphene to be the core of their research due to its minimum thermal noise. The research was published in the IOP 2D Materials Journal and was funded by the EU Graphene Flagship, EPSRC, ERC and Nokia Technologies.

Dr. Shakil, in his lab
Dr. Shakil, a Lecturer at the School of Computing, Electronics and Mathematics at Plymouth University elucidated the fact that the electromagnetic properties of graphene over a broad range of frequencies are poorly understood in scientific communities. Initially their research was misguided due to the masking signals of a supporting substrate, metallic contacts and measurement probes. However, they finally managed to successfully theorise the properties of graphene which will aid various semiconductor physics applications.
