用同步辐射粉末衍射法测定了Sb-Te二元系δ相的晶体结构。它清楚地表明，许多金属间化合物，这取决于化合物的组成，具有不同的堆叠周期，存在于这个阶段。这些结构是基于立方ABC堆叠结构，两种基本结构单元在原子水平上沿堆叠方向形成沿着共生。这些化合物的化学式表示为Sb（2n）Te 3，其中n是整数，堆叠层数为2n + 3。在堆叠周期和Te浓度之间存在反比例关系。
The crystal structure of the delta-phase in the Sb-Te binary system has been determined by synchrotron powder diffraction. It is clearly shown that many intermetallic compounds, which have different stacking periods depending on compound composition, exist in this phase. These structures are based on the cubic ABC stacking structure, and two kinds of fundamental structural units form an intergrowth along the stacking direction at the atomic level. The chemical formulae of these compounds are expressed as Sb(2n)Te3, where n is an integer and the number of stacking layers is 2n + 3. There is a relationship of inverse proportionality between the stacking period and the Te concentration.
