Tuning the Spin Transition and Carrier Type in Rare-Earth Cobaltates via Compositional Complexity (Adv. Mater. 47/2024)

Abstract

Compositional Site Disorder Enables Engineering Oxide Phase Transitions

Work by Elliot J. Fuller and co-workers demonstrates that tunable disorder in a crystal can be quite useful: compositional site disorder was used to modify oxide semiconductors by changing the carrier type, improving crystallinity and tuning a spin transition. Applications include electrothermal thresholding devices such as radio frequency limiters. More details can be found in article number 2406885.
