Investigation of deposition rate effects on the current-voltage characteristics of organic dynamic random access bistable devices

Abstract

We, investigate organic dynamic random access bistable devices with A1/Alq(3)/n-type Si structure at different deposition rates. Each of them contains a heterostructure, and only two-layer deposition is needed in this structure. Current-voltage characteristic similar to that of metal/organic semiconductor/metal structure, the three-layer structure widely used for organic memory devices, is obtained. Moreover, we able to modify the electrical properties by utilizing appropriate deposition rates. This device shows extremely simple fabrication process and great potential in future advanced organic flexible display.
