Effect of Humidity on the Writing Speed and Domain Wall Dynamics of Ferroelectric Domains (Adv. Electron. Mater. 6/2022)

Ferroelectric Thin Film-Based Memories In article number 2100650, Gustau Catalan, Neus Domingo, and co-workers demonstrate that the maximum speed at which ferroelectric thin film-based memories can be written accelerates with atmospheric humidity – and, conversely, slows down in dry conditions. The domain width as a function of relative humidity follows the behavior of the water adsorption isotherm, revealing the interplay between water layer thickness and screening.
