Record-Setting Phototransistor is Flexible and Sensitive

Facebook X LinkedIn Email
Inspired by mammals' eyes, a record-setting phototransistor could improve the performance of myriad products — from digital cameras, night-vision goggles and smoke detectors to surveillance systems and satellites — that rely on electronic light sensors. Developed at the University of Wisconsin-Madison, the phototransistor can be shaped to fit different optical systems, unlike similar devices that are fabricated on rigid surfaces. The device has a back-gate configuration based on transferrable single-crystalline Si nanomembrane. A unique phototransistor developed by...Read full article

    phototransistor
    A solid-state device similar to an ordinary transistor except that incident light on the PN junctions regulates the response of the device. It offers built-in gain and a greater sensitivity than that of photodiodes.
