Organic semiconductors are currently attracting great attention as a useful material for opto-electronic devices such as light-emitting diodes and field effect transistors. To optimize such device performances, the orientation control of the molecules in the thin film state is very important, because their optical and transportation properties show significant anisotropies To control the molecular orientation, the roles of substrates and growth conditions in physical vapor deposition have been investigated. However, highly oriented thin films of organic semiconductors have not been obtained to date. It is well known that high magnetic field orients organic single crystals. In this study, we aimed at magnetic field as a new parameter of orientation control of organic thin films, and the effects on orientation of some organic semiconductors and self-assembled monolayers were investigated.

有机半导体目前正在引起极大的关注，作为光电设备（例如发光二极管和现场效应晶体管）的有用材料。为了优化这种设备性能，在薄膜状态下分子的方向控制非常重要，因为它们的光学和运输特性显示出明显的各向异性以控制分子方向，因此已经研究了底物的作用和生长条件在物理蒸气沉积中的作用。但是，迄今为止尚未获得有机半导体的高度定向的薄膜。众所周知，高磁场会导致有机单晶。在这项研究中，我们将磁场作为有机薄膜方向控制的新参数，并研究了对某些有机半导体和自组装单层的方向的影响。
