Effect of Diameter, Length, and Chirality on the Properties of Silicon Nanotubes

The mechanical properties of nanostructures are a researcher’s favorite topics. In the meantime, and physical two dimensional structures nanotubes have attracted greater attention due to their wide application. Si (Si) consisting atoms that arranged as honeycombs. This structure has created some special in nanotubes. this paper, Young’s modulus values stress strain diagrams investigated using molecular dynamics method Tersoff potential. Then, changes effect size dimension was for closer look. For purpose, nanotube diameter, length, chirality shift from zigzag armchair were studied. results showed fracture decreased with increasing length nanotube. It also shown stronger than zigzag. diameter change on it observed no specific order could be found between strength. good agreement other studies.
