Title:
ULTRA HIGH−SPEED PHOTOELECTRIC SIGNAL CONVERSION ELEMENT
Document Type and Number:
WIPO Patent Application WO/2003/028116
Kind Code:
A1
Abstract:
A ultra high−speed photoelectric signal conversion element comprising a thin film (3) forming a light detection unit (5) provided on a substrate (4) and a pair electrodes (2) provided thereon across the light detection unit. The thin film constituting the light detection unit is formed of a solid phase transition material, and the pair of electrodes are formed of a superconducting material. The photoelectric signal conversion element can handle the light signal of pico second order and follow the ON−OFF signal of tera Hertz.
