Qurv Technologies, a Spain-based startup established in 2020 to develop wide-spectrum image sensors based on graphene and quantum-dot technologies, has developed a sensor that combines the unique electronic properties of graphene with suitable quantum nanoparticles as light sensitizers. The new device reportedly enables efficient detection of a broad range of wavelengths from ultraviolet to infrared light all concentrated into one simple device.
The production and transfer process of graphene leverages existing scalable Complementary Metal Oxide Semiconductor (CMOS) manufacturing processes. Furthermore, this graphene-based sensor could replace traditional costly alternatives based on indium gallium arsenide, paving the way to SWIR imagers up to 1000 times cheaper.
