【摘要】 本文进行了如下具有创新性的研究工作。在自行设计的水平式有机晶体的气相沉积装置中,进行了并五苯单晶薄膜的重复性再生长研究。以并五苯薄膜为有源层,先后制备了多类有机场效应器件,研究了场的作用下载流子的注入特性,实现了并五苯有源层的双极载流子传输,这些为实现有机电泵浦激光器所需要的电子、空穴均衡注入提供了新的途径。以多种工艺在硅基衬底和玻璃衬底上制备了不同结构的有机薄膜场效应晶体管（OTFT）,论述了不同制备工艺的优缺点,以及器件结构对性能的影响。制备的全有机薄膜场效应晶体管最高迁移率接近1 cm²/Vs,开关电流比超过10⁵。采用全蒸镀方式制备了双极并五苯薄膜场效应迁移率,其空穴迁移率为0.17 cm²/Vs,电子迁移率为2.0×10^-2 cm²/Vs。提出双栅绝缘层结构全有机薄膜场效应晶体管,达到了减少器件栅的漏电流、降低器件工作电压和提高器件工作电流的目的。并在此基础上设计和制备了OTFT-OLED全有机集成像素。更多还原

【Abstract】 The information technology has become the global stratagem technology. Based on the photoelectron and microelectronics, communication and net technology has become the core of high-tech. As the main carriers of information technology, lasers and display devices play significant roles. Compare to the inorganic semiconductors, the organic semiconductors have much advantages. The semiconductor photo-electronic devices and field-effect devices with organic semiconductor acting as active layer have wide application foreground, and become one of the research hotspots.Physical vapor deposition in horizontal system is used to grow the pentacene single crystal thin-film. By repeatedly experiments, the condition of pentacene single crystal growth is optimized.For the research of electrically pumped organic lasers, the carrier injection is considered as the key questions of carrier imbalance injection and low mobility in organic materials. With the pentacene acting as the active layer, the diode of ITO/pentacene/Al, the vertical organic thin-film field-effect transistor, the organic thin-film ambipolar field-effect transistor and the organic thin-film double-field-effect transistor are fabricated. The devices performances are researched and the ambipolar carriers injection in pentacene is successfully realized, which supply a new way for electron and更多还原
