Strontium titanate is a material of considerable interest for electronic applications. A recent study revealed that strontium titanate (STO) annealed in strontium oxide (SrO) powder exhibits large ...

Positron Annihilation Spectroscopy (PAS) is a highly sensitive, non-destructive method for probing atomic-scale imperfections in a broad spectrum of materials, from metals and ceramics to polymers and ...

Defect engineering is the deliberate introduction, removal, or manipulation of structural imperfections in nanomaterials to tailor their properties for specific applications. Unlike the traditional ...
