Cantilevered single walled boron nitride nanotube based nanomechanical resonators of zigzag and armchair forms

► SWBNNT of zigzag and armchair forms are modeled as molecular structural mechanics based FE model. ► Resonant frequency variations to attached mass is analyzed for mass sensitivity analysis. ► Higher order modes are explored for detection of added mass and its location identification. ► Mass sensitivity analysis in terms of different atomic structures of SWBNNT is performed.
