We study the heat generation in quantum dot system with Fano resonance by nonequilibrium Green's functions method. The Fano resonance influences the heat generation significantly. As ξ increases, the heat generation decreases gradually. From the study of Q-eV curves, we find that the linewidth function Γ has huge influence on the heat generation. The Q-eV curves display obvious steps when the linewidth function Γ is small. However, these steps disappear with Γ increasing. As the source-drain bias eV increases, the Q-eV g curves also display interesting behaviors. 相似文献
