Organic Memristive Device

This chapter is dedicated to the detailed technical description of polyaniline based organic memristive devices. Namely this memristive device is the key element of neuromorphic system which are the protagonist in this book. Main material of the device active channel is polyaniline (PANI), because it can vary its conductivity in a wide range according to the doping-dedoping and/or redox state. Polyelectrolyte (PEO) is the other important material of the device, as it provides the possibility of redox reactions, responsible for the resistance switching. It is considered the architecture and assembling techniques of these devices, as well as electrical characteristics in DC and pulse modes. It is suggested the qualitative explanation of the resistance switching in such devices, basing on data, obtained from IR and Raman spectroscopies and X-ray fluorescence. The strategies of the optimization of the devices properties are also considered.
