Poor crystallinity
WebJul 20, 2016 · However, the inherent limitation in diffusion of intermediate species during solid-state polymerization results in poor crystallinity of as-prepared CN. 16, 17 By using molten salts as the solvent, the crystallinity was largely improved, but the resulting product was virtually inactive in photocatalytic reactions because of the occurrence of a ... WebMar 30, 2024 · Lattice defect engineering has attracted attention due to its ability to develop thermoelectric materials with low thermal conductivity. For Mg2Si single crystals (SCs), Si vacancy (VSi) defects can be introduced and consequently result in the formation of dislocation cores. These lattice defects confer Mg2Si SCs with a lower thermal …
