Computing and comparative analysis of topological invariants of symmetrical carbon nanotube Y junctions

Abstract

Single-walled branched carbon nanotubes are highly favorable building blocks of next-generation innovative nanoelectronics and nanodevices. Y junctions as members of this family have shown great potential for the production of nanoscale three-terminal devices and carbon nanotube networks. The bond energy is among the most essential thermophysical quantities to be considered when studying chemical materials for different purposes in various fields of science and technology. To estimate the bond energy of symmetrical single-walled armchair carbon nanotube Y junctions, we are presenting a mathematical formula defined in structural parameters of Y junctions. Moreover, some linear, multiple linear and non-linear regression models described in terms of some topological indices have been presented. According to the best of our knowledge and literature, this is the first such report about this family of junctions.
