Researchers design graphene-based charge-injection photodetectors

Researchers at Zhejiang Universityת University of California, The Chinese University of Hong Kong, Peking University, Aalto University, University of Cambridge and Nanjing University have developed a new graphene-based photodetector that could detect light within a broader bandwidth. Their device could be used to develop new and more advanced imaging technologies.

The teams work is based on traditional charge-coupled device (CCD) and complementary metal-oxide-semiconductor (CMOS) imaging technologies. The researchers stated that their imaging devices, combining CCD’s MOS photogate for high sensitivity and CMOS’s independent pixel structure, can significantly benefit monolithic integration, performance, and readout.
