Higher frequencies mean faster data transfer and more powerful processors. Technically, however, it is anything but easy to keep increasing clock rates and radio frequencies. New materials could solve the problem. Experiments at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have now produced a promising result: Researchers were able to get a novel material to increase the frequency of a terahertz radiation flash by a factor of seven: a first step for potential IT applications.
