Graphene-based terahertz detector is ultra-thin, flexible
The researchers expect such flexible detectors to be easily replicated and used in larger arrays for a wide range of applications, from imaging (THz camera) for automotive applications to substances identification (one application envisioned would be skin-level cancer detection) or wireless communications in the tens of gigabits per second.

A single detector, with a gate length and channel width of 5.5μm and 4μm, respectively, exhibited a voltage responsivity above 2V/W, with an estimated noise equivalent power (NEP) below 3nW/√Hz at 487GHz.
The research published in the scientific journal Applied Physics Letters under the title “A flexible graphene terahertz detector” has been funded by the EU Graphene Flagship, the Swedish Foundation for Strategic Research (SSF), and the Knut and Alice Wallenberg Foundation (KAW).
