Future of Data is Graphene
Indeed, scientists are reaching the end of the road for certain technologies for high-speed data transfer and are seeking new materials for the future of components for the processors responsible for this aspect of our ever more connected world. A material like graphene has the potential to be one of those materials.
The material is especially attractive because it works very well for exceptionally high electronic frequencies, extending into the technologically important terahertz (THz) range where most conventional electronic materials fail, researchers noted.
Prior to their latest work, the team had achieved a new understanding of the physics behind nonlinearity, which is now known as the thermodynamic picture of ultrafast electron transport in graphene, he said. But until now, they did not know how to control this property, “which was the missing link with respect to using graphene in everyday technologies,” Turchinovich said.

A team of researchers at the Institute of Laser Engineering, Osaka University, in collaboration with Bielefeld University and Technical University Braunschweig in Germany, came closer to unraveling the complicated optical response of wide-bandgap semiconductor multiple quantum wells and how atomic-scale lattice vibration can generate free space terahertz emission. Their work provides a significant push towards the application of laser terahertz emission microscopes to nano-seismology of wide-bandgap quantum devices.
Terahertz (THz) waves can be generated by ultrafast processes occurring in a material. By looking at THz emission, researchers have been able to study different processes at the quantum level from simple bulk semiconductors to advanced quantum materials such as multiple quantum wells (Fig.1).

Abstract:
How can large amounts of data be transferred or processed as quickly as possible? One key to this could be graphene. The ultra-thin material is only one atomic layer thick, and the electrons it contains have very special properties due to quantum effects. It could therefore be very well suited for use in high-performance electronic components. Up to this point, however, there has been a lack of knowledge about how to suitably control certain properties of graphene. A new study by a team of scientists from Bielefeld and Berlin, together with researchers from other resea
