Charge-Injection-Controlled Organic Transistor
Abstract:New-type organic transistors based on the charge injection process at organic/metal interface were proposed and demonstrated. The device was composed of an organic deposited film sandwiched by two metal electrodes and the third stripe-shaped electrode embedded in the organic film. The output current corresponding to collector current was modulated by the applied voltage of the third electrode corresponding to base electrode, and current amplification factor of hFE reached 20. The transistor operation was attributed to the electron injection caused by accumulation of holes supplied from the base electrode. The current amplification was observed up to about 100 Hz in the frequency response measurement.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
