文摘
We derive by the Schwinger source theory method, the power spectrum of photons, generated by charged particle moving within 2D sheet, with index of refraction n. Some graphene-like structures, for instance graphene with implanted ions, or, also 2D-glasses, are dielectric media, enabling the experimental realization of the Vavilov–Čerenkov radiation. The relation of the Vavilov–Čerenkov radiation to LED, where the 2D additional dielectric sheet is the integral part of LED, is discussed. It is not excluded that LEDs with the 2D dielectric sheets will be the crucial components of detectors in experimental particle physics.
