High-speed photocurrent multiplication devices using codeposited films of copper phthalocyanine and fullerene were fabricated. The photoresponse time for the light-on and -off reached 3 and 15 ms, respectively, which were in striking contrast to those for single fullerene films requiring several seconds. Performance of the present device is promising for the application to multiplication-type photodetector.
