Graphene amplifier unlocks hidden frequencies in the elusive terahertz wavelengths – Could mean safer X-Rays and other revolutionary possibilities
Terahertz waves (THz) sit between microwaves and infrared in the light frequency spectrum, but due to their low energy, scientists have been unable to harness their potential. The conundrum is known in scientific circles as the "terahertz gap."Being able to detect and amplify THz waves (T-rays) would open up a new era of medical, communications,...
