| Popis: | International audience; A large effect of pressure on the thermal conductance of silicon/carbon nanotube junctions is shown to result from induced anharmonicity at the interface. Through atomistic simulations, we demonstrate the opening of pressure induced inelastic phonon channels, which are responsible for a several fold increase of the thermal conductance. |
