Show more >Graphene is a new material that is promising for application in microwave electronics as it features high mobility and is compatible with standard nanofabrications techniques. Graphene is also extremely sensitive to the environment due to its two dimensional nature, is mechanically robust, biocompatible, and can be easily functionalized. As such, graphene based devices are good candidates for high-speed biosensors. In this work, we present flexible back-gated graphene transistors where the channel is exposed, an important difference with standard high frequency field effect transistors (FETs). We present DC and RF characterization to demonstrate solid performances, then we discuss transconductance measurements and their scaling as a function of channel width. These results can be helpful for design of high-speed graphene based biosensors where large sensing areas and high speeds are needed.Show less >
