Scientists create Quantum Tunneling in Graphene to provide Terahertz wireless communication

Scientists create Quantum Tunneling in Graphene to provide Terahertz wireless communication
The Silicon Review
02 March, 2021

Researchers from MIPT, Moscow Pedagogical State University, and the University of Manchester have developed a highly sensitive terahertz detector based on quantum-mechanical tunneling in graphene. This device has proven to be superior to the other commercially available analogs based on semiconductors and superconductors made with other materials and particles other than graphene. This will further improve the speed of telecommunication services.

The information transfer in wireless networks is primarily based on the transformation of high-frequency electromagnetic waves that travel continuously in a discrete sequence. This technique is known as modulation. The researchers have stated that graphene has shown such characteristics, allowing the free transfer of electromagnetic particles in a synchronized form by increasing the maximum operating frequency and increasing the distance between the waves.

The scientists' discovery will open new doors and insights for graphene-based detector applications in wireless communications, security systems, radio astronomy, and medical diagnostics. The research contents and the results of this experiment are published in the highly ranked journal Nature Communications. The results presented in this paper are an example of a successful collaboration between several research groups.
