Organic thin-film transistors of phthalocyanines
Pure and Applied Chemistry, 2008Abstract Organic thin-film field-effect transistors (OTFTs) are emerging as attractive candidates for low-price, large-area, and flexible circuit applications. A variety of organic compounds have been utilized as active semiconductor materials for OTFTs, among which phthalocyanine compounds have attracted considerable attention owing to ...

Heterojunction organic thin-film transistors
1995 53rd Annual Device Research Conference Digest, 2002We have developed a unique organic transistor structure which enables us to realize both p-channel and n-channel operation in a single device. This device also demonstrates the applicability of heterojunction concepts to organic semiconductors. The active material consists of two layers: the first layer, typically 10-20 nm thick, is made up of /spl ...

Stability of Organic Thin Film Transistors
MRS Proceedings, 2004AbstractThe stability of organic thin film transistors (OTFTs) has become one of the most vital issues in this area of research. In this report, we investigated the stability of rubber stamp printed OTFTs. The electrical properties such as saturation field effect mobility, threshold voltage and on/off current ratio change significantly in ambient air ...

Stabilization of organic thin film transistors by ion implantation
Physica B: Condensed Matter, 2012We report on the effects of low energy ion implantation (N and Ne) in the reduction and control of the degradation of pentacene organic thin film transistors (OTFTs) due to the exposure to atmosphere (i.e. oxygen and water). We have observed that a controlled damage depth distribution preserves the functionality of the devices, even if ion implantation

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

On the Origin of Contact Resistances of Organic Thin Film Transistors
Advanced Materials, 2012A model is presented that describes the gate-voltage-dependent contact resistance and channel-length-dependent charge carrier mobility of small-molecule-based organic thin-film transistors in top and bottom drain/source contact configuration.

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.
