Why are Vacancies and Interstitials Important in Nanotechnology?
These defects are particularly crucial in nanotechnology for several reasons:
1. Enhanced Properties: They can dramatically alter the electrical, thermal, and mechanical properties of nanomaterials. For instance, vacancies can increase electrical conductivity or modify magnetic properties. 2. Catalytic Activity: Interstitials can act as active sites for catalysis, enhancing the reactivity of nanoparticles. 3. Diffusion: The presence of vacancies facilitates the diffusion of atoms, which is essential for processes like sintering in nanoparticle fabrication.
