Over 60 young researchers from all over the world will
It is the EU's largest ever research initiative, the Graphene Flagship, coordinated by Chalmers, who organises the school this week, 25-30 June 2017. This year it is held in Sweden with focus on electronic applications of the two-dimensional material with the extraordinary electrical, optical, mechanical and thermal properties that make it a more efficient choice than silicon in electronic applications. Andrei Vorobiev is a researcher at the Department of Micro Technology and Nanoscience at Chalmers as well as one of the many leading experts giving lectures at Graphene Study and he explains why graphene is suitable for developing devices operating in the THz range:
"One of the graphene's special features is that the electrons move much faster than in most semiconductors used today. Thanks to this we can access the high frequencies (100-1000 times higher than gigahertz) that constitutes the terahertz range. Data communication then has the potential of becoming up to ten times faster and can transmit much larger amounts of data than is currently possible", says Andrei Vorobiev, senior researcher at Chalmers University of Technology.
Researchers at Chalmers are the first to have shown that graphene based transistor devices could receive and convert terahertz waves, a wavelength located between microwaves and infrared light, and the results were published in the journal IEEE Transactions on Microwave Theory and Techniques. One example of these devices is a 200-GHz subharmonic resistive mixer based on a CVD graphene transistor integrated on silicon that could be used in high-speed wireless communication links.
