WebJun 1, 1998 · (2) The optical-beam-induced resistance change caused by heating can be observed when the aperture size is zero without interference from the photo current caused by electron-hole-pair generation. In the conventional OBIRCH method, the laser beam creates not only the resistance change, but also the photo current that can mask the resistance ... Optical beam induced resistance change (OBIRCH) is an imaging technique which uses a laser beam to induce a thermal change in the device. Laser stimulation highlights differences in thermal characteristics between areas containing defects and areas which are defect-free. As the laser locally heats a defective area on a metal line which is carrying a current, the resulting resistance changes can be detected by monitoring the input current to the device. OBIRCH is useful for dete… north bernard https://kolstockholm.com
