The two-dimensional material graphene, consisting of a single layer of carbon, possesses unique properties of interest for a wide range of applications. In particular, the unique electronic features of graphene, combined with its flexible nature, make it a promising material to integrate into plastic and fabric, something that will be important building blocks in a future interconnected world. We have demonstrated a flexible terahertz detector that detects signals in the frequency range 330 GHz to 500 GHz. Hopefully, this can extend the use of terahertz technology to applications that will require flexible electronics, such as wireless sensor networks and wearable technology. Moreover, we study charge carrier transport properties in graphene field-effect transistors (GFETs), and fabrication processes, with the aim to improve graphene technology for high frequency applications. Part of the work is within the Graphene flagship.
