In this study, electrically bistable devices were fabricated by incorporating cuprous sulfide (Cu2S) nanospheres with mean size less than 10 nm into a poly(N-vinylcarbazole) (PVK) matrix. A remarkable electrical bistability was clearly observed in the current–voltage curves of the devices due to an electric-field-induced charge transfer between the dodecanethiol-capped Cu2S nanospheres and PVK. The...
