综述了碲化镉和碲锌镉的生长方法。在简要介绍了有关Cd-Te体系相平衡的最新结果之后，讨论了Cd-Te化学键的特性对Cd-Te晶体生长的影响。在此基础上，从宏观和微观两个方面阐述了锌在CdTe中的合金化行为。此外，对合金中锌偏析引入的应变进行了估算，并显示出与CZT CRSS相近的应变。最后提出并讨论了CZT生长中的一些改进措施：CZT化学计量比的调整，合金中锌浓度的均匀性问题和应变问题，这些问题可以通过微重力生长、自由液体表面自晶化、固态再结晶和/或去湿来克服。(2015Wiley-VCH Verlag GmbH&Co.KGaA，Weinheim)
The CdTe and CdZnTe growth are reviewed. After presenting briefly the most recent results concerning the phase equilibria in the Cd-Te system, the impact of the characteristics of the Cd-Te chemical bond on the CdTe crystal growth are discussed. The behaviour of Zn alloying in CdTe is then presented at macroscopic and microscopic scale. Furthermore, the strains introduced by the Zn segregation in the alloys are estimated and shown close to the CZT CRSS. Some improvements in the CZT growth are finally presented and discussed: the adjustment of the CZT stoichiometry, the Zn concentration uniformity issue and the strain issue in the alloys which can be overcome by microgravity growth, self-seeding from a free liquid surface, solid state recrystallization and/or dewetting.
