Record-breaking photodetector captures light in just 125 picoseconds
Record-breaking ultrathin photodetector captures light across the entire spectrum in just 125 picoseconds, opening the door to powerful new imaging technologies.
Electrical engineers at Duke University have created the fastest pyroelectric photodetector ever demonstrated, a device that detects light by sensing the tiny amount of heat it produces when absorbed. The ultrathin sensor can capture light across the entire electromagnetic spectrum. It operates at room temperature, requires no external power source, and can be integrated directly into on-chip systems. The technology could eventually enable a new generation of multispectral cameras with applications in areas such as skin cancer detection, food safety monitoring, and large scale agriculture. The findings were reported in the journal Advanced Functional Materials.
