Negative differential thermal resistance in a double-chain system
چکیده انگلیسی
Using nonequilibrium molecular dynamics simulations, we study the phenomenon of negative differential thermal resistance (NDTR) in a double-chain system. We investigate the dependence of NDTR on the external potential, inter- and intra-chain interaction and the system size. It is reported that the NDTR can occur in a small double-chain system with weak external potential and weak inter- and intra-chain interaction. We also present the influence of the external potential, inter- and intra-chain interaction and the system size on the heat current of the system through the phonon spectral analysis.
