A facile solution process for the fabrication of organic single crystal semiconductor devices which meets the demand for low-cost and large-area fabrication of high performance electronic devices is demonstrated. In this paper, we develop a bottom-up method which enables direct formation of organic semiconductor single crystals at selected locations with desired orientations. Here oriented growth of one-dimensional organic crystals is achieved by using self-assembly of organic molecules as the driving force to align these crystals in patterned regions. Based upon the self-organized organic single crystals, we fabricate organic field effect transistor arrays which exhibit an average field-effect mobility of 1.1 cm(2)V(-1)s(-1). This method can be carried out under ambient atmosphere at room temperature, thus particularly promising for production of future plastic electronics.
我们展示了一种用于制造有机单晶半导体器件的简便溶液处理方法，该方法满足了低成本和大面积制造高性能电子器件的需求。在本文中，我们开发了一种自下而上的方法，该方法可以在选定的位置以所需的取向直接形成有机半导体单晶。在这里，通过使用有机分子的自组装作为驱动力，将一维有机晶体定向生长，从而在图案化区域中对准这些晶体。基于自组织的有机单晶，我们制造了有机场效应晶体管阵列，其平均场效应迁移率为 1.1 cm(2)V(-1)s(-1)。这种方法可以在室温下的环境气氛中进行，因此对于未来的塑料电子学的生产具有很大的应用潜力。
