High-responsivity photo-EMF receivers for laser ultrasonics

High-responsivity photo-EMF receivers for laser ultrasonics

We describe the development of photo-EMF detectors that retain the adaptive advantages of conventional EMF receivers, while significantly improving responsivity. These EMF detectors use asymmetric interdigitated contacts (AIDC) to reduce the carrier transit time to increase the photoconductive gain....
