摘　　要：对InGaAsP/InGaAs组成的超晶格,基底为InP的固体微制冷器进行了初步研究,发现热电和热电子转换同时存在于超晶格微制冷器中。提出了简化后的物理模型,具体分析了影响热电转换效率的热阻和电阻、制冷影响因素和误差等因素,计算结果与实际器件接近。The superlattice micro-cooler is capable of the potential thermoelectric conversion of high efficiency, which has attracted much attention of researchers. This paper makes a preliminary research into the In-GaAsP/InGaAs superlattice cooler whose substrate is InP, finding that both thermoeletric and thermionic conversion occours in superlattice micro-cooler. This paper presents the simplified physical model and analyzes the factors of thermal resistance and electric resistance influencing the efficiency of thermoelectric conversion. The calculating results correspond with the experimental results, which provides the basis of analysis to optimize the micro-cooler.
