Size dependance of mechanical stiffness in silicon nanowire.

The present present the effect of orientation of silicon nanowires on its band structure properties based on atomic interaction within SiNWs. It was observed the atomic interaction energy resulted in inducing force which created both repulsive or attractive generating free radicals which produce dynamic behaviour leading to band structure shrinkage. This effect has been observed in various theoretical studies for nanowires. At fixed position, the atom within the silicon significantly interact, resulting in relative molecular vibration.
