Graphene-CMOS High-Res Sensor Images Visible and IR Light at the Same Time

Facebook Twitter LinkedIn Email Comments
Graphene instead of silicon has been used for a CMOS integrated circuit, resulting in a high-resolution image sensor consisting of hundreds of thousands of photodetectors based on graphene and quantum dots (QDs). This graphene-QD CMOS sensor can be operated as a digital camera that is highly sensitive to light in the UV, visible and IR wavelengths (300 to 2000 nm). The sensor could enable a wide range of optoelectronic applications, such as low-power optical data communications and compact and ultra-sensitive sensing systems. Graphene-quantum dots-CMOS-based sensor for ultraviolet,...Read full article
