We propose a model for a three-terminal quantum well heat engine with heat leakage.According to the Landauer formula,the expressions for the charge current,the heat current,the power output and the efficiency are derived in the linear-response regime.The curves of the power output and the efficiency versus the positions of energy levels and the bias voltage are plotted by numerical calculation.Moreover,we obtain the maximum power output and the corresponding efficiency,and analyze the influence of the heat leakage factor,the positions of energy levels and the bias voltage on these performance parameters.
