The novel material graphene and its technological applications are studied at the Vienna University of Technology. Now scientists have succeeded in combining graphene light detectors with semiconductor chips.
Today, most information is transmitted by light – for example in optical fibres. Computer chips, however, work electronically. Somewhere between the optical data highway and the electronic chips, photons have to be converted into electrons using light-detectors. Scientists at the Vienna University of Technology have now managed to combine a graphene photodetector with a standard silicon chip. It can transform light of all important frequencies used in telecommunications into electrical signals. The scientific results have now been published in the journal “Nature Photonics”.
