Each Grain Different in Its Own Way: Size-Dependent Pseudosymmetry in Fivefold Twinned Nanoparticles Mapped by 4D-STEM
{{output}}
Geometric frustration arises when geometry prevents the simultaneous satisfaction of local interactions, producing pseudosymmetry and emergent behaviors. Pseudosymmetric features in crystalline nanomaterials are known to appear as local strain and distortion, ... ...
