چکیده

We investigated visible and UV light response of OTFTs based on the solution processable poly(3-hexylthiophene) (P3HT) semiconducting polymer. The transistors show a photoresponse in channel current under white and UV light illumination. Stabilization time after illumination and recovery time after turning off the light sources are also studied. A transport analysis based on a modified drift-diffusion model is presented.

A Comparative Study of the Gas Sensing Behavior in P3HT- and PBTTT-Based OTFTs: The Influence of Film Morphology and Contact Electrode Position

Bottom- and top-contact organic thin film transistors (OTFTs) were fabricated, using poly(3-hexylthiophene-2,5-diyl) (P3HT) and poly[2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene] (PBTTT-C16) as p-type channel semiconductors. Four different types of OTFTs were fabricated and investigated as gas sensors against three volatile organic compounds, with different associated dipole moments...

Two-dimensional MoS2-assisted immediate aggregation of poly-3-hexylthiophene with high mobility.

Nanoscale morphology is of significance to the electronic properties of semiconducting polymers. Solution-processed poly-3-hexylthiophene (P3HT) has been demonstrated as a promising active-layer material in organic thin film transistors (OTFTs) and solar cells. Controlling the crystallinity of P3HT chains is critical for gaining high-performance devices. Here we demonstrated the immediate cryst...

Solvent Vapor Treatment Effects on Poly(3-hexylthiophene) Thin Films and its Application for Interpenetrating Heterojunction Organic Solar Cells

The solvent vapor treatment (SVT) for poly(3-hexylthiophene) (PAT6) films and its application to interpenetrating heterojunction organic solar cells have been studied. It was found that SVT could improve the crystallinity and electrical characteristics of the PAT6 films. We fabricated organic solar cells with an interpenetrating structure of PAT6 and fullerenes utilizing the SVT process, and di...

Hole mobility enhancement by chain alignment in nanoimprinted poly„3-hexylthiophene... nanogratings for organic electronics

The authors report that the poly 3-hexylthiophene-2,5-diyl P3HT nanogratings shaped by nanoimprint lithography show enhanced hole mobility and strong anisotropy of conductance due to nanoimprint-induced three-dimensional polymer chain alignment. Field effect transistors were fabricated using these nanogratings and device measurements show a hole mobility of 0.03 cm2 /V s along the grating direc...
