    at terahertz frequencies

## Description

- description: Ultrafast and sensitive (noise equivalent power < 1 nWHz-1/2) light-detection
    in the Terahertz (THz) frequency range (0.1-10 THz) and room-temperature (RT)
    is key for applications such as time-resolved THz spectroscopy of gases, complex
    molecules, and cold samples, imaging, metrology, ultra-high-speed data communications,
    for capturing snapshots of ultrafast dynamics at the nanoscale, coherent control
    of quantum systems or quantum optics. Here, we report RT THz nano-receivers exploiting
    antenna-coupled graphene field effect transistors integrated with lithographically-patterned
    high-bandwidth (~100 GHz) chips, operating with a combination of high speed (hundreds
    ps response time) and high sensitivity (noise equivalent power ~120 pWHz-1/2).
    Remarkably, this can be achieved with various antenna and transistor architectures
    (single gate, dual gate) for any frequency in the 0.1-10 THz range, thus paving
    the way for the design of ultrafast graphene arrays in the far infrared, opening
    concrete perspective for targeting the aforementioned applications.
