New T-wave detector uses waves of the electronic sea in graphene

A team of researchers from Russia, Great Britain, Japan, and Italy has created a graphene-based terahertz detector. Their device doubles up as a sensitive detector and a spectrometer operating in the terahertz range, and it's also a tool for studying plasmons in two-dimensional materials. All of these things existed before, but they took up a whole optical table. Researchers packed the same functionality into a dozen micrometers.
