OFET Characteristics of Stretched Poly(3-hexylthiophene) Films

Superficial wrinkles in stretched, drying gelatin films.

When a thin film of initially hydrated gelatin is allowed to dry from the surface, superficial changes in the structure of the material affect the local mechanical properties of the drying region. If the film is simultaneously subjected to large strain deformation (above 20%), a periodic pattern of wrinkles appears on the surface of the gelatin along the length of the sample in the direction of...

Microfluidic supercritical antisolvent continuous processing and direct spray-coating of poly(3-hexylthiophene) nanoparticles for OFET devices.

We report for the first time the use of a microfluidic supercritical antisolvent process (μSAS) to synthesize semiconducting polymer nanoparticles (NPs) of poly(3-hexylthiophene) (P3HT). Solvent-free P3HT NPs with average diameters as small as 36 ± 8 nm are obtained. They are continuously spray-coated on substrates to fabricate OFET devices, demonstrating hole mobility through the nanoparticle ...

Temperature Variation Effects on I-V Characteristics of Cu-Phthalocyanine based OFET

In this study we present the effect of elevated temperatures from 300K to 400K on the electrical properties of copper Phthalocyanine (CuPc) based organic field effect transistors (OFET). Thin films of organic semiconductor CuPc (40nm) and semitransparent Al (20nm) were deposited in sequence, by vacuum evaporation on a glass substrate with previously deposited Ag source and drain electrodes with...

Thermophysical properties of free-standing micrometer-thick Poly (3-hexylthiophene) films

Enhanced visible photoluminescence in ultrathin poly(3-hexylthiophene) films by incorporation of Au nanoparticles.

Incorporation of non-luminescent dodecanethiolate-protected gold clusters into regioregular poly(3-hexylthiophene) films results in a 6-fold increase in the visible photoluminescence (PL) of the polymer, which arises predominantly from NP-induced structural changes in the composite films.
