Analysis of longitudinal vibration band gaps in periodic carbon nanotube intramolecular junctions using finite element method

The longitudinal vibration band gaps in periodic (n, 0)–(2n, 0) single-walled carbon nanotube(SWCNT) intramolecular junctions(IMJs) are investigated based on the finite element calculation. The frequency ranges of band gaps in frequency response functions(FRF) simulated by finite element method (FEM) show good agreement with those in band structure obtained by simple spring-mass model. Moreover, a comprehensive parametric study is also conducted...
