Graphene pushes the speed limit of light-to-electricity conversionNature Nanotechnology
Two of them, of course! That’s why we’re giving away two Graphene Touch SPEED racquets to just one winner. Get ready to double your luck! The prizes 3rdPRIZE When Novak steps out on court he carries the Djokovic 12R Monstercombi on his shoulders. ...
Graphene's excellent conductive properties make it attractive to researchers. Even at room temperature, electrons pass through the material effortlessly, near the speed of light and with little resistance. This means a graphene interconnect would likely stay much cooler than a copper interconnect of th...
Computing by Controlling the Speed of Light “It’s like the wind is blowing against one sprinter while helping the other run faster,” explained Pintus, who led the experimental work at UC Santa Barbara. “By applying a magnetic field to the memory cells, we can control the speed of ligh...
information carried by light to be converted into electrical information that can be processed in electrical circuits. Graphene is an excellent material for ultrafast conversion of light to electrical signals, but so far it was not known how fast graphene responds to ultrashort flashes of light. ...
In addition, the modulation bandwidth of a laser is ultimately limited by the large damping at high injection current levels due to gain compression. Recently, nanoLEDs that utilize the Purcell effect were proposed as fast and efficient nanoscale light sources to address the limitations of ...
3a. The responsivity of either PD is close to 0.1 A/W at the −0.3 V-bias voltage. The lines in Supplementary Fig. 9 show that the photocurrents increase with the light input, indicating the dominated photoconductive effect20,43 in graphene-based PD without additional gate voltage ...

Micro/nanoprocessing of graphene surfaces has attracted significant interest for both science and applications due to its effective modulation of material properties, which, however, is usually restricted by the disadvantages of the current fabrication m
2, 2019 — In order to increase the speed with which photonic integrated circuits (PICs) control light flux, researchers are investigating new materials with high optical nonlinearity. Among the promising materials are microwaveguides based on graphene, a material in which charge carrier concentrations...
