Abstract

We report the application of reduced graphene oxide, using vitamin C as reducing agent, to make a composite with poly(vinyl phenol) as the active layer of write-once-read-many times memory devices. These devices present a high ON/OFF current ratio of 105 when read at 1 V, retain the information for a long time maintaining the ON/OFF current ratio constant, and require low energy for performing at 5 V the memory write (less than 10-8 J cm-2 device active area) and read operations.
