In Situ Heating STEM of the Thickness‐Dependent Evolution of Ferroelastic Domains

Small, EarlyView.
In‐situ heating scanning transmission electron microscopy combined with machine‐learning segmentation is used to study the thickness and temperature dependent behavior of ferroelastic domain walls in free‐standing LaAlO3 samples. The results quantify domain wall curvature and density throughout cooling, revealing a pronounced thickness‐dependent ...
