Notes:
Based on the assumption that sp3 hybridization is more stable in bulk silicon, this studyis a step forward in understanding the structures and mechanical properties of silicon nanotubes(SiNT). Using the well tested form of Tersoff potential we have calculated cohesive energy andother parameters for SiNT of various diameters and chiralities. Using this potential, the resultsobtained for bulk silicon are satisfactory, so we expect that the same potential would work well withSiNT as well. We calculated Young’ modulus and shear modulus for SiNT. Young’s modulus liesin the range of 100- 200 GPa which is about 10-20 times lower than CNT and shear modulus liesbetween 200-300 GPa. This work shall motivate further theoretical and experimental work in thefield of nanostructures
