Current Reduction Mechanism of Organic Thin Film Transistor
Extended Abstracts of the 2009 International Conference on Solid State Devices and Materials, 2009Hidden origin of current reduction mechanism in organic thin film transistor (OTFT) structure is investigated based on a device simulation, which makes it possible to derive current–voltage (I–V) characteristics, potential distribution and carrier concentration inside a device by solving Poisson's equation and continuity equation. It is made clear

An organic thin film transistor structure for optoelectronic applications
SPIE Proceedings, 2004In this work we present an innovative structure for organic Thin Film Transistors (TFTs) that is transparent, flexible, and optimized for a good behaviour at relatively high frequencies. Starting from a basic structure, several possible options for building such kind of structure can be implemented.

Flexible Organic Thin-Film Transistors for pH Monitoring
IEEE Sensors Journal, 2009A novel freestanding flexible device based on an organic field effect transistor (OFET), able to detect pH changes in chemical solutions thanks to a functionalized floating-gate, was realized and successfully tested. The device is assembled on a flexible film (Mylar), which acts at the same time as gate insulator and as mechanical support for the whole

Organic thin film transistors with double insulator layers
Microelectronics Journal, 2007We have investigated a double-layer structured gate dielectric for the organic thin films transistor (OTFT) with the purpose of improving the performance of the SiO"2 gate insulator. A 50nm PMMA layer was coated on top of the SiO"2 gate insulator as organic insulator layer. The results demonstrated that using inorganic/organic compound insulator as the

Effect of morphology on organic thin film transistor sensors
Analytical and Bioanalytical Chemistry, 2005This review provides a general introduction to organic field-effect transistors and their application as chemical sensors. Thin film transistor device performance is greatly affected by the molecular structure and morphology of the organic semiconductor layer. Various methods for organic semiconductor deposition are surveyed.
