已经实现了 PTH 在高度取向的 PE 基底上从气相外延结晶。 PTH 在高度取向的 PE 基板上外延生长导致板条状 PTH 晶体的形成。板条状PTH晶体表现出良好的有序结构，其长轴优先平行于PE基底晶体的链方向，而小部分PTH板条状晶体的长轴垂直于PE基底晶体的链方向排列。电子衍射进一步证明 PTH 在定向 PE 基板上的外延结晶导致 PTH 与薄膜平面中的 c 轴和 b 轴对齐。 PTH 的 c 轴优先垂直于 PE 链方向，或者平行于 PE 链方向（较少见）。前者源于二维晶格匹配，而后者仅基于一维分子间匹配。观察到的外延生长为制备大面积井孔提供了有效的方法...
Epitaxial crystallization of PTH on highly oriented PE substrate from vapor phase has been achieved. The epitaxial growth of PTH on highly oriented PE substrate leads to the formation of lathlike PTH crystals. The lathlike PTH crystals exhibit well-ordered structure with their long axes preferentially parallel to the chain direction of the PE substrate crystals, while a small part of PTH lathlike crystals aligned with their long axes perpendicular to the chain direction of the PE. Electron diffraction further demonstrates that the epitaxial crystallization of PTH on oriented PE substrate results in an alignment of PTH with the c- and b-axes in the film plane. The c-axis of PTH is oriented either perpendicular, preferentially, or parallel, less frequently, to the PE chain direction. The former originates from a two-dimensional lattice matching, while the latter is based only on a one-dimensional intermolecular matching. The observed epitaxial growth provides an effective way for preparing large area well-a...
