Ambipolar Multi‐Stripe Organic Field‐Effect Transistors
Advanced Materials, 2011Here we demonstrate a new architecture for ambipolar device, termed multi-stripe OFET (MSOFET), where the current flows through a planar array of precisely-defined sub-micrometric stripes (wires) made of two types of highly-ordered organic ...

Monolayer organic field-effect transistors
Science China Chemistry, 2019Monolayer organic field-effect transistors (OFETs) are attracting worldwide interest in device physics and novel applications due to their ultrathin active layer for two-dimensional charge transport. The monolayer films are generally prepared by thermal evaporation, the Langmuir technique or self-assembly process, etc., but their electrical performance

All-organic field effect transistors
MRS Proceedings, 2003AbstractIn this work we present fully patterned organic transistors based on selective electropolymerization of conducting polymers that enables simple fabrication of micron scale features. It involves fabrication of pentacene field effect transistors in which the conducting, insulating parts as well as the substrate are all made of polymers.

On the degradation of organic field-effect transistors
Proceedings. The 16th International Conference on Microelectronics, 2004. ICM 2004., 2005Degradation experiments with organic thin film transistors (OTFT) made of the p-conducting organic semiconductor pentacene revealed a distinct dependence of the electrical transistor parameters to the ambient conditions. A sample that was kept unprotected in dark ambient air conditions was found to be still operating after 9 months of degradation.

Bio-organic field effect transistors
SPIE Proceedings, 2007This paper reports on the use of new DNA-based biopolymers as the semiconducting layer in field effect transistors. Thin-film field effect transistor (FET) structures are fabricated with two different DNA-biopolymers as semiconductor layers, and two different field effect transistor structures are studied.

Advances in organic field-effect transistors
Journal of Materials Chemistry, 2005Since organic field-effect transistors (OFETs) were first described in 1987, they have undergone great progress, especially in the last several years. Nowadays, the performance of OFETs is similar to that of amorphous silicon (a-Si : H) devices and they have become one of the most important components of organic electronics.

Organic field-effect bipolar transistors
Applied Physics Letters, 1996Organic field-effect transistors (FETs) which employ two carefully selected active materials can function as n channel, p channel, or both n- and p-channel devices. It is shown that under an appropriate set of bias conditions the channel current in FETs with α-hexathienylene (α-6T) and C60 active layers consist of electron and hole components that are ...

Molecular materials for organic field-effect transistors
Journal of Physics: Condensed Matter, 2008Organic field-effect transistors are important applications of thin films of molecular materials. A variety of materials have been explored for improving the performance of organic transistors. The materials are conventionally classified as p-channel and n-channel, but not only the performance but also even the carrier polarity is greatly dependent on ...

Theory of the organic field-effect transistor
Synthetic Metals, 1999A method is described to derive the mobility of organic field-effect transistors (OFETs) by using the current-voltage characteristics at low drain voltage. After correction for the contact series resistance, it appears that the mobility of sexithiophene (6T) and octithiophene (8T) is gate bias dependent, which actually corresponds to charge ...
