We are standing at the beginning of the industrialization of flexible thin-film transistor (TFT) backplanes. The two important research directions for the TFTs are (i) processability on flexible substrates and (ii) sufficient field-effect mobilities of electrons and holes to support complementary metal insulator semiconductor operation. The most important group of TFT capable semiconductors are the several modifications of silicon films: amorphous, nanocrystalline and microcrystalline. We summarize their TFT properties and their compatibility with foil substrate materials. 相似文献

Organic field‐effect transistors (OFETs) are used to investigate the evolution of the solid‐state microstructure of blends of poly(3‐hexylthiophene) (P3HT) and [6,6]‐phenyl C61‐butyric acid methyl ester (PC61BM) upon annealing. Changes in the measured field‐effect mobility of holes and electrons are shown to reveal relevant information about the phase‐segregation in this system, which are in agreement with a eutectic phase behavior. Using dual‐gate OFETs and in‐situ measurements, it is demonstrated that the spatial‐ and time‐dependence of microstructural changes in such polymer:fullerene blend films can also be probed. A percolation‐theory‐based simulation is carried out to illustrate how phase‐segregation in this system is expected to lead to a substantial decrease in the electron conductivity in an OFET channel, in qualitative agreement with experimental results. 相似文献

Organic thin film transistors: Materials,processes and devices 总被引:1,自引:0,他引:1

For the past ten years, organic materials have been extensively investigated as an electronic material for thin film transistor
(TFT) devices. Organic materials offer strong promise in terms of properties, processing and cost effectiveness and they can
be used in flat panel displays, imagers, smart cards, inventory tags and large area electronic applications. In this review,
we summarize the current status of the organic thin film transistors including substrate materials, electrodes, semiconducting
and dielectric layers; organic thin film preparation methods; morphological studies for organic thin films; electrical characterization
of gate dielectric layers and semiconducting active layers; and characterization of the OTFTs. Future prospects and investigations
required to improve the OTFT performance are also given.
This paper is dedicated to Professor Hyun-Ku Rhee on the occasion of his retirement from Seoul National University. 相似文献
