Memory devices based on small organic molecules donor-acceptor system

摘要

For the last a few decades the interest in using organic materials in electronic applications (light emitting diodes, field effect transistors, solar cells, etc) has increased rapidly. Recently, organic materials have also been used to realise electronic memory devices. These devices show two electrical conductance states ("high" and "low") when voltage is applied. The memory effect in these devices with simple structure based on a thin film of nano-sized particles and/or small molecules embedded in an organic layer was demonstrated. This work investigates organic memory devices based on organic materials-blend between small organic molecules (TTF and TCNE) and polymer (PVAc).
