2D-Dirac materialen voor terahertz-band nanoantennes.

This proposal for research aims to study nanoantennas based on 2D Dirac materials (2DDMs): Graphene and Topological insulators (TIs). Microelectronics has already fulfilled many expectations for daily use in the fields of mobile phones, the automotive industry, sensors, etc. This has been achieved by the size reduction from macroscopic to microscopic scales of chips and transmitting devices, as well as to their increasing frequency range. However, the need for faster and more portable systems able to communicate between themselves at high rates, is greater than ever and requires that we continue shrinking the size of the electronic devices down to nano scales. State of the art microelectronic designs are now confronted with the issue of decreasing the size of devices like antenna, while keeping working at the usual frequencies. The terahertz (THz) band is a scientifically rich but technologically limited frequency band, since THz wave emitters and receivers are less developed, compared to its neighboring bands (microwave and optical). Nano-antennas based on 2DDMs for wireless communications could solve this issue. In this work, the physical principles that govern the interactions of EM waves and 2DDMs in THz region will be investigated to guide us on the search for optimal structures of nanoantennas. The project aims to investigate the electronic and THz radiation properties of 2DDMs.
