Abstract:The main purpose of the present work is to establishing a correspondence between mechanical deformation and transport properties, which is presumably useful in nano-sensor applications. As a byproduct of this study, the potential differences in the mechanical behavior of armchair and zigzag tubes, as well as that of armchair-zigzag junctions, is also revealed. It is concluded that a significant change in conductance usually is accompanied by severe deformations. For large bending angles a gap widening is observed for both the semiconducting and kink structures. It is observed that I-V characteristics indeed depend on the bending angle, hence the possibility of usage as nano-sensor.
