Vibrational characteristics of single-layered boron nitride nanosheet/single-walled boron nitride nanotube junctions using finite element modeling

This paper aims to investigate the vibrational properties of single-layered boron nitride nanosheet/single-walled boron nitride nanotube junctions. To this end, the finite element (FE) (approach is employed.Considering the similarity of molecular mechanics and structural mechanics, the mechanical properties of the utilized FE approach can be derived. The junctions with nanotubes at one side and both sides of the nanosheet are considered. It is shown that the frequencies of both sides located nanotubes are always larger than those of one side located nanotube. Moreover, the influences of geometrical parameters of nanosheet and nanotube on the frequencies of boron nitride nanosheet/nanotube junctions are studied. It is observed that the vibrational behavior of the considered junctions has an inverse relation to the nanotube and nanosheet dimensions. (paper)
