Organic ISFET Based on Poly (3-hexylthiophene)
نویسندگان
چکیده
We have fabricated organic field-effect transistors (OFETs) with regioregular poly(3-hexylthiophene) (P3HT) operable at low-voltages in liquid solutions, suitable for in vitro biosensing applications. Measurements in electrolytes have shown that the performance of the transistors did not deteriorate and they can be directly used as ion-sensitive transducers. Furthermore, more complex media have been tested, with the perspective of cell analysis. Degradation effects acting on the device operating in liquid could be partly compensated by adopting an alternate current measuring mode.

Organic thin-film phototransistors based on poly(3-hexylthiophene)
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-di...

متن کاملPrinting highly efficient organic solar cells.
The technological attraction in organic solar cells is their compatibility to printing processes. However, up to today, nearly no literature on "printed" organic solar cells have been published and the major body of the research work was done by spin coating or blading techniques. Transferring the spin-coating or doctor blading process currently used for the fabrication of bulk heterojunction s...
متن کاملA Combined Experimental and Theoretical Study of Optoelectronic and Structural Properties of a New Copolymer Based on Polyvinylcarbazole (PVK) and Poly (3-hexylthiophene) (PHT)
In this paper we report on a combination of experimental and theoretical study of a new copolymer based on carbazole and methylthiophene (Cbz-Mth), in their neutral and oxidized states. We discuss the influence of chain length on conformational and optoelectronic properties with the DFT method. Conformational analysis shows that there are no big changes in the structural parameters of neutral o...
