Inelastic electron transport in C70 fullerene

The effect of inelastic electron-phonon interactions on thermoelectric and electron transport properties of the C-70 molecule has been studied. The results show that thermopower sign is positive for negative energies; while for positive energies it reverses its sign. A linear graph via energy with staircase structure is seen for thermopower of the Coo molecule by considering inelastic electron-phonon interactions. In addition, rate of entropy production and the figure of merit of C-70 cages have been studied to get more insight of the thermoelectric properties of C-70 molecules. The values of ZTs are in the range 0 - 2x10(-4) and the effect of single contacts is small on the values of ZT.
