Nonvolatile nano-crystal floating gate OFET memory with light assisted program

In this paper, gold (Au) nanocrystals based nonvolatile floating gate OFET memory devices with light assisted program are studied. Programmable memory characteristics were observed according to the programming/erasing operations and the memory window and on/off memory ratio were dramatically improved from 18 V, 102 to 63 V, 105 through light assisted program, respectively. Good reliability was confirmed by the data retention and endurances characteristics. Therefore, this method has potential applications in organic memory devices and integrated circuits.
