Graphene is often portrayed as the ultimate conductor, thanks to its flexibility and to its excellent conductivity. However, research has shown that the electrical and the structural quality of graphene are intimately connected, and that nanoscale lattice deformations caused by surface corrugations limit the mobility of electrons in graphene.

Terahertz imaging of graphene paves the way to industrialization
Terahertz imaging of graphene paves the way to industrialization.As X-ray scans revolutionized non-invasive medical treatments, terahertz spectroscopy penetrates graphene films allowing scientists to make detailed maps of their electrical quality, without damaging or contaminating the material.
Now Europeâs Graphene Flagship has brought together researchers from academia and industry to develop and mature this analytical technique, and created a novel measurement tool for graphene characterisation.

X-ray scans revolutionised medical treatments by allowing us to see inside humans without surgery. Similarly, terahertz spectroscopy penetrates graphene films allowing scientists to make detailed maps of their electrical quality, without damaging or contaminating the material. The Graphene Flagship brought together researchers from academia and industry to develop and mature this analytical technique, and now a novel measurement tool for graphene characterisation is ready.
The effort was possible thanks to the collaborative environment enabled by the Graphene Flagship European consortium, with participation by scientists from Graphene Flagship partners DTU, Denmark, IIT, Italy, Aalto University, Finland, AIXTRON, UK, imec, Belgium
