Exploring Novel Polar Topologies for Low Power Nano-electronics

Description: Devices based on nanoscale ferroelectric polarisation structures with unusual polar topologies overturn the classical idea that our electronic circuits need to consist of fixed hardware components. Ferroelectric domain walls, polar vortices and polar skyrmions can be easily created, destroyed and moved about simply by an applied stimulus, without harming the crystal structure, thus making them ideal for reconfigurable electronics. At the same time, their diverse physical properties, which are distinct from those of the host material, combined with their dynamic nature and low power requirements, bring new functionality to a range of devices, including transistors and capacitors for conventional logic and storage, and memristive elements for neuromorphic computing. However, to harness their true potential there is a great deal of fundamental physics yet to uncover. As domain walls are usually only a few atoms thick and highly dynamic, it is essential to characterise them at the relevant spatial and temporal scale.
