Changes in carbon nanotube electronic properties by collisions with inert gases
- Conference date: 6-13 March 2004
- Location: Kirchberg, Tirol (Austria)
Collisions with inert gases increase the thermoelectric power and resistivity of single‐walled carbon nanotube (SWNT) thin films as M∼1/3, where M is the mass of the colliding gas. Molecular dynamics simulations show that there is a similar mass dependence for the collision‐induced deformation and phonon excitation of SWNTs, which suggests that the electron scattering is due to the induced dents and/or phonons. The simulations also show that the M∼1/3 dependence is obtained under a wide range of collision conditions (e.g., SWNT temperature, incident scattering angle and colliding gas energy).
