N2 - In the thermal-assisted data storage technologies, the behavior of heat transfer in nano-tip during thermomechanical data bit formation process is a critical factor affecting the areal storage density, data bit writing/reading speed and system reliability. In this paper, the thermal properties of a nano-tip are analyzed using the nonequilibrium molecular dynamics simulation, which is based on the Tersoff-type three-body potential and the Gear's five-value predictor-corrector integration algorithm. For comparison, a nano-cube is also simulated. The simulated results show that the effects of the nano-structural configuration and boundary conditions on the thermal transport are remarkable, which can be attributed to the phonon boundary-scattering and possible phonon spectrum modification. Finally, the thermal conductivities of the nano-tip and the nano-cube are calculated.
