中文摘要：
本文利用传输矩阵法数值模拟了电子在加入周期性正负偏压的双势垒（＂摇摆＂棘齿）异质结中的传输特性,获得了两电子库间的净电流以及所伴随的净热流的表达式.进一步分析了净电流、净热流和制冷系数等性能参数的特征,获得的结果对介观热电子器件的研制有一定的理论指导意义.
英文摘要：
In this paper, the transport characteristics of the electrons in the double-barrier heterostructure under adding periodic positive and negative bias （＂rocked＂ ratchet） are numerically simulated by the transfer matrix method. The expressions of net current and net heat flow between the two electronic reservoirs are obtained. Further, the performance characteristics of net current, net heat flow and coefficient of performance are analyzed. The results obtained here may provide some significant guidance for the design and manufacture of mecro-thermoelectric devices.
