| Research Abstract |
In order to realize high performances of carbon nanotube (CNT) devices, understanding of the dynamics in the structural-change process and the lattice-vibration transport in the thermal transport in addition to the static electromechanical properties is necessary. We have investigated that 1) an energy dissipation mechanism for a resonant vibration of CNT cantilevers from their Q factors, 2) the lattice-vibration transport from the thermal transport properties, 3) the dynamics of plastic deformation and junction formation of CNTs by direct observation, and 4) the relationship between the electrical properties and topological defects by analyzing electrical properties in the dynamics process.
