Abstract

Organic semiconductors have electrical and optical properties that are useful for certain applications. Photoconductors based on semiconducting organics and polymers are used in commercial products and light-emitting diodes are close to commercialization. Field-effect transistors are promising for use in low-cost applications such as displays, electronic tags, and sensors. This presentation will describe important properties of organic field-effect devices and review the characteristics and prospects of circuits and systems based on organic transistors. Integration scales have approached the LSI level and a variety of new fabrication methods have been developed. A new type of injection laser based upon the field-effect transistor geometry and crystalline organic semiconductors has been successfully realized. The structure and operation of such lasers will be outlined.
