Organic Thin Film Field-effect Transistors (otfts) Are Organic Thin Film Transistors
particularly interesting as their fabrication processes are much less complex compared with conventional Si technology, which involves high-temperature and high-vacuum deposition processes and sophisticated photolithographic patterning methods. In general, low-temperature deposition and solution processing can replace the more complicated processes involved in conventional Si technology. In add...
متن کاملDNA adsorption measured with ultra-thin film organic field effect transistors.
Organic ultra-thin film field effect transistors (FET) are operated as label-free sensors of deoxyribonucleic acid (DNA) adsorption. Linearized plasmid DNA molecules (4361 base pairs) are deposited from a solution on two monolayers thick pentacene FET. The amount of adsorbed DNA is measured by AFM and correlated to the concentration of the solution. Electrical characteristics on the dried DNA/p...
متن کاملField-Effect Mobility of Organic Polymer Thin-Film Transistors
We present a method of extracting the field-effect mobility from the transfer characteristics of organic polymer thin-film transistors (OP-TFTs), in both the linear and saturation regimes, by accounting for the dependence of the mobility on the gate bias, which translates to a dependence on the accumulated density of majority charge carriers in the channel. This method is compared to the common...
متن کاملStable organic thin-film transistors
Organic thin-film transistors (OTFTs) can be fabricated at moderate temperatures and through cost-effective solution-based processes on a wide range of low-cost flexible and deformable substrates. Although the charge mobility of state-of-the-art OTFTs is superior to that of amorphous silicon and approaches that of amorphous oxide thin-film transistors (TFTs), their operational stability general...
متن کاملBias stress effect in low-voltage organic thin-film transistors
The bias stress effect in pentacene organic thinfilm transistors has been investigated. The transistors utilize a thin gate dielectric based on an organic self-assembled monolayer and thus can be operated at low voltages. The bias stress-induced threshold voltage shift has been analyzed for different drain-source voltages. By fitting the timedependent threshold voltage shift to a stretched expo...
