In recent years, a series of investigations has been devoted to a possibility of using crystals based on CdTe with addition of magnesium (Mg), selenium (Se), or manganese (Mn) for X and gamma radiation detectors. In the literature there are contradictory data with respect to the segregation of Mg in (Cd,Mg)Te and Se in Cd(Te,Se) and to the possibility of obtaining materials with a homogeneous composition without grains and twins.

We have wide technological possibilities of preparing crystals and investigating some of their properties. Thus, we performed crystallizations of (Cd,Mg)Te, Cd(Te,Se), (Cd,Mn)(Te,Se), and (Cd,Mn)Te compounds. The aim of our studies was to check whether any of the investigated materials may be easily obtained by the Low Pressure Bridgman (LPB) method in the form of large, homogeneous, high resistivity single crystals with as few as possible twins, subgrains, and tellurium inclusions.

The crystallization processes were performed by using the LPB method. The elements used: Cd, Te, Mn, Mg, and Se were of the highest purity available at that time. In order to obtain reliable conclusions the crystallization processes were carried out under identical technological conditions. The details of our technological method and the results of the investigation of physical properties of the samples are presented below.

近年来，一系列研究致力于将基于 CdTe 的晶体添加镁 (Mg)、硒 (Se) 或锰 (Mn) 用于 X 和伽马辐射探测器的可能性。在文献中，关于 Mg 在 (Cd,Mg)Te 中的偏析和 Se 在 Cd(Te,Se) 中的偏析以及获得具有无晶粒和孪晶的均匀成分的材料的可能性，存在相互矛盾的数据。

我们在制备晶体和研究它们的一些特性方面拥有广泛的技术可能性。因此，我们对 (Cd,Mg)Te、Cd(Te,Se)、(Cd,Mn)(Te,Se) 和 (Cd,Mn)Te 化合物进行了结晶。我们研究的目的是检查是否可以通过低压布里奇曼 (LPB) 方法以大的、均匀的、高电阻率的单晶形式轻松获得任何研究材料，其中孪晶、亚晶粒和碲尽可能少夹杂物。

结晶过程是通过使用 LPB 方法进行的。使用的元素：Cd、Te、Mn、Mg 和 Se 是当时可用的最高纯度元素。为了获得可靠的结论，结晶过程在相同的工艺条件下进行。我们的技术方法的细节和样品物理性质的研究结果如下所示。
