Article Synopsis
- The study focuses on ion migration in solid electrolytes, which is crucial for devices like batteries and fuel cells.
- A planar sandwich structure is created by depositing tungsten oxide films on a substrate, allowing sodium ions (Na+) to diffuse into the films during the process.
- The research visualizes Na+ migration, revealing changes in the film's geometry and resistance, and explains these changes through mechanical deformation and varying ion mobility, potentially enhancing ion control in functional devices.
Phase-change materials are the basis for next-generation memory devices and reconfigurable electronics, but fundamental understanding of the unconventional kinetics of their phase transitions has been hindered by challenges in the experimental quantification. Here we obtain deeper understanding based on the temperature dependence of the crystal growth velocity of the phase-change material AgInSbTe, as derived from laser-based time-resolved reflectivity measurements. We observe a strict Arrhenius behaviour for the growth velocity over eight orders of magnitude (from ~10 nm s(-1) to ~1 m s(-1)).
