研制了一套便携式超高真空分子束沉积系统，用于有机薄膜、多层膜和超晶格的合成、原位和实时X射线衍射测量。该系统已被优化为小尺寸，同时仍然包含在分子束外延（MBE）条件下实现薄膜生长所需的全部功能。它可以单独用于薄膜生长，也可以运输和安装在标准衍射仪上。此外，它可以对接到一个固定的多用途分子束外延生长系统的样品转移，从而允许更广泛的增长和表征。该系统的设计和性能的报告，强调所需的修改存款有机材料。为了证明实时X射线散射实验的能力，给出了在Ag（111）衬底上外延生长3，4，9，10-二萘嵌苯四甲酸二酐的研究的一些初步结果。
A portable UHV molecular beam deposition system has been developed for synthesis, in situ, and real-time x-ray diffraction measurements of organic thin films, multilayers, and superlattices. The system has been optimized for small size, while still incorporating full features necessary to achieve thin film growth under molecular beam epitaxy (MBE) conditions. It can be used independently for thin film growth, or it can be transported and mounted on standard diffractometers. Additionally, it can be docked to a stationary multipurpose MBE growth system for sample transfer, thus permitting more extensive growth and characterization. The design and performance of this system are reported, with emphasis on modifications required to deposit organic materials. To demonstrate the capabilities for real-time x-ray scattering experiments, some preliminary results of a study of epitaxial growth of 3,4,9,10-perylene-tetracarboxylic dianhydride on Ag(111) substrates are given.
