热电材料是利用晶体内部载流子的电、热输运来实现热电相互转换的一种功能材料，又称为温差电材料。低的热导率、高的电导率、大赛贝克系数、高功率因子为常用的评估性能好的热电材料的参数。研究者已探索出多种优良的热电材料，部分具有较高的应用性，但目前该领域的突破多数集中在n型导电材料上，而热电器件需要性能同样优良的p型和n型材料相匹配才能够实现最大的转化效率。本文以寻找性能优良的p型原料为目标，以Zn-Sb-Mg三元相图为基础，选出53个数据点，进行大通量的制备与表征，作出性能测评，从而探究三种金属的不同配比对材料性能的影响，并作出三维性能分布图，以此促进和完善p型半导体材料的研发，进而推动热电器件的广泛应用。

Thermoelectric material, also known as thermoelectric material, is a kind of functional material which uses the electric and thermal transport of the internal carriers of the crystal to realize the conversion of thermoelectricity. Low thermal conductivity, high electrical conductivity, high Seebeck coefficient and high power factor are commonly used parameters for evaluating thermoelectric materials with good performance. Researchers have explored a variety of excellent thermoelectric materials, some of which have high applicability, but the breakthrough in this field by now is mainly focused on the N type conductive materials, at the same time, the thermoelectric devices need to match the P type and N type materials with the same excellent performance to achieve the maximum conversion efficiency. In order to find the P material with excellent performance, 53 data points are selected on the basis of the phase diagram of the Zn-Sb-Mg system . Large flux preparation and characterization are made, as well as the performance evaluation. Thus we explored the influence of the different ratio of three metals on the material performance, then made the three-dimensional trend map. The research and development of materials will further promote the wide application of thermoelectric devices.
