Organic reversible switching devices for memory applications

A new organic switching device that behaves like a thyristor and has a potential for organic memory applications is presented. The predictable device critical voltage values permit devices to be designed with the required characteristics. The device has a switching time shorter than 0.5 ms and can switch several thousand times, basic requirements for commercial viability. One of the advantages of poly(methylmethacrylate-co-9-anthracenyl-methyl-methacrylate) (MDCPAC) is that it is a methacrylate derivative, a polymer excellent mechanical properties in the form of thin films. The production of the switches describe is cheap and involves a simple technology, compatible with established organic electronic device construction processes.
