Due to its zero-gap electronic stmcture, large graphene sheets are not suitable for FET applications [185, 193]. It has been shown that graphene transistors conduct current even at the point of expected isolator behavior (i.e., Dirac point) [288]. Therefore, current modulation cannot be achieved using macroscopic graphene sheets [185]. In order to have a band gap on graphene, the use of narrow ribbons of...

Radiation methods occupy an important place in the production and investigation of new functional materials, devices, and systems of nanometer size (ion-track membranes, polymeric nanocomposites, 3D nanostructures, metal nanoparticles, carbon nanostructures, etc.). The recent trend towards electronic miniaturization places at the forefront the problem of fabrication of semiconductor nanostructures, which is possible only with the use of radiation lithographic methods. The radiation modification of graphene can play a key role in the development of a new generation of industrial microchips based on graphene transistors, which will lead to a sharp increase in the operation speed and recording density of modem computer and communication systems.
