中文摘要：
研究了在具有不同温度和不同化学势的两个热库中电子通过一个三势垒纳米线异质结构进行传输的问题,利用传输矩阵法得到了电子的传输概率,进而算出了电子传输所产生的热流.通过数值计算绘出了电子制冷机的性能特征曲线.分析了偏压和异质结结构对制冷机性能的影响,重点讨论了中间势垒高度和宽度对电子传输概率、制冷率和制冷系数的影响.
英文摘要：
In this paper,the electron transports through a three-barrier nanowire heterostructure between two reservoirs with different temperatures and chemical potentials are studied.The transport probability of electron is obtained by using the transfer matrix method,and the heat flow carried by the electrons transfer is calculated out.The performance characteristic curves of the refrigerator are plotted by numerical calculations.The influence of bias voltage and heterostructure on the performance of the refrigerator is analyzed.Especially,the effects of the height and the width of the middle barrier on transport probability,cooling rate,and colling coefficient are emphasized.
