Crystalline Thin-Film Organic Devices

通过这个项目，我们将一种全新的范式引入有机电子：高度结晶的有机半导体将作为厚的多层膜生长在各种衬底上，从而避免静电无序的不利影响，并实现高性能的垂直传输设备。关键问题是寻找如何实现这种有序生长的一般规律，包括衬底性质、生长方法、生长条件、层的掺杂和分子的选择。薄膜的性质将通过各种结构、光谱和电子方法进行研究。这种新型的高度有序薄膜将被用来实现到目前为止还不可能实现的先进器件概念：尤其是，我们希望实现高性能的垂直有机晶体管，其开关速度远远超过目前的有机晶体管。此外，我们希望实现第一个有机双极晶体管，利用高度有序的有机薄膜中的长载流子扩散长度。最后，我们努力实现了一个电泵浦的有机微腔激光器。

With this project, we introduce a radically new paradigm into organic electronics: Highly crystalline organic semiconductors will be grown as thick multilayer films on various substrates, allowing to avoid the detrimental influence of static disorder and realize high-performance vertical transport devices. Key issues are to find general rules how such ordered growth can be achieved, including substrate properties, growth method, growth conditions, doping of the layers, and choice of molecules. The properties of the films will be investigated by a variety of structural, spectroscopic and electronic methods. The novel highly ordered films will be used to realize advanced device concepts not possible so far: in particular, we wish to realize high-performance vertical organic transistorsreaching switching speeds far beyond current organic transistors. Also, we wish to realize the first organic bipolar transistor, leveraging the long carrier diffusion lengths in highly ordered organic films. Finally, we strive to realize an electrically pumped organic microcavity laser.
