Introduction to Nanoionic Elements for Information Technology

This chapter provides the basic definitions of nanoionic redox-based resistive switching elements, their main switching modes, and their most important performance parameters. Furthermore, it sketches the scope of this book, which spans from nanoscale physics and chemistry of the switching phenomenon to devices, technology, and application areas. Three types of redox-based resistive switching elements are introduced, and a brief history of the phenomenon and the designated device application is given. This is followed by a discussion of the performance requirements and the specific themes of the application in memories and of the application in logic circuits, concluding with prospects and challenges.
