Organic Thin-film Field-effect Transistor, Light-emitting And Display-driving

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...
