New graphene applications: Ultra-fast photodetector and terahertz generator

Photodetectors made with graphene can process and conduct both light signals and electric signals extremely fast. Upon optical stimulation, graphene generates a photocurrent within picoseconds. Until now, none of the available methods were fast enough to measure these processes in graphene. Scientists have now developed a method to measure the temporal dynamics of this photo current.
