Scientists from Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have fabricated an economical and energy-efficient wafer-scale photodetector (thin slice-based) using gold \u2013 silicon interface, for security applications.<\/p>\n\n\n\n
It could help detect weak scattered light as an indication of unwanted activity.<\/p>\n\n\n\n
The gold (Au)-silicon (n-Si) interface shows high sensitivity towards light demonstrating the photodetection action.<\/p>\n\n\n\n
The method is highly economical and enables large-area fabrication without compromising the detector response.<\/p>\n\n\n\n
The process of fabrication is quick and takes only minutes to fabricate a detector of any arbitrary area.<\/p>\n\n\n\n
The detector exhibits a rapid response of 40 microseconds and can detect low light intensities. The device covers a broad spectral range from Ultraviolet to Infrared.<\/p>\n\n\n\n
The detector operates in the self-powered mode so that it does not require external power for its operation and makes it energy efficient.<\/p>\n\n\n\n
The device is also environmentally stable and can be used under harsh conditions for several days.<\/p>\n","protected":false},"excerpt":{"rendered":"
