Tunable graphene microribbons made to respond to terahertz light

Researchers from Berkeley built a microscale device that responds to light at terahertz frequencies. The device is an array made of graphene microribbons. By varying the width of the ribbons and the concentration of charge carriers in them, the scienstists were able to control the collective oscillations of electrons (plasmons) in the microribbons.
