Monolithic electronic devices based on domain wall motion in a ferroelectric crystal

Ferroelectric domain watt motion can provide the basis for monolithic electronic devices which are able to gate, amplify, perform digital logic, read out permanent analog messages, provide digital shift register storage, and scan optical images. No use of ferroelectric coercivity is made in these devices. Most of the functions have been experimentally demonstrated in simple form. The basic operating principles of these devices are explained, and their material requirements are discussed. The specific operation of five categories of devices is described.
