ELECTRON TRAPPING OPTICAL READ/WRITE/ERASE MEMORY

RECENTLY HIGH EFFICIENCY PHOSPHORS HAVE BEEN DEVELOPED AT QUANTEX. THESE MATERIALS CONTAIN EXTREMELY REPRODUCIBLE TRAPS, THEREFORE THEY ARE CALLED ET MATERIALS. THE ELECTRON TRAPPING FROM VISIBLE LIGHT PRODUCES EXTREMELY LONG TERM STORAGE, WHICH CAN BE INSTANTLY INTERROGATED BY INFRARED TO PRODUCE A VISIBLE OUTPUT. CONSEQUENTLY, A TOTALLY PHOTONIC READ/WRITE/ERASE MEMORY CAN BE CONSTRUCTED. IT IS PROPOSED TO FABRICATE EXPERIMENTAL FILM STRUCTURES WITH THESE ET MATERIALS AND EVALUATE PHOTONIC MEMORY PROPERTIES, IN TERMS OF INFORMATION DENSITY, THROUGHPUT RATES, SIGNAL-TO-NOISE RATIO, ETC.
