Fabrication and Characterization of Organic Transistors using Poly(triarylamine)-based Amorphous Semiconductor by Spin-coating Method

Abstract

Organic electronics is revolutionary technology aimed at unconventional electronic device on transparent substrate and will probably rely on poly(triarylamine) (PTAA) semiconductors for organic transistor fabrication. The devices described in this paper, through fabrication, measurements and extraction of transistor parameters are organic transistor having PTAA as an active semiconductor thin films by spin-coating method. The PTAA films were investigated by X-ray diffraction (XRD) to reveal the film structure orientation. The PTAA-based organic transistors exhibited a field-effect mobility () of 2.68 x 10-2 cm2 /Vs. Tthe gate voltage operation well until -11V with the threshold voltage of 13.21V and also current on/off ratio18.23.
