Ferroelectric Domain Wall Memory and Logic

Powered by big data and artificial intelligence, data-centricinnovationsare bringing about transformative societal changes and are expectedto continue to meteorically rise for the foreseeable future, necessitatingan accelerated development of alternative miniatured electronics andcomputing, which surmount the traditional latency and energy issuesof von Neumann computing. One such highly attractive avenue involvesthe exploration of electrically programmable topological nanostructures,such as domain walls in ferroelectrics the atomically abruptnanoscale interfaces. The ferroelectric domain walls are agile andresponsive to external stimuli. This allows selective control overtheir position, conformation, and functionality, which is ultimatelythe key to realizing low-energy memory and computing structures. Thistopical article examines the technological applications of ferroelectricdomain walls for high-density information storage, logic, and computingapplications and offers insights into potential future developmentsincluding challenges and opportunities.
