A two-terminal organic electronic device with a single active layer, composed of an electron-donor-type conjugated polymer, an electron-acceptor-type small organic molecule and an insulating polymer, is investigated for non-volatile memory applications, as presented by Jae-Eun Park, Jae-Hoon Eom, Taehoon Lim, Do-Hoon Hwang, and Seungmoon Pyo on page 2188. The image describes chemical structures of components of the active layer and the schematic device structure. The active layer is formed through a simple spin-coating process. The devices are expected to work as a switching and memory element due to the co-existence of electron-donor- and -acceptor-type materials. The device performance can be improved by controlling the composition of the active layer.
