“…Yet, it might be important to distinguish bulk properties of the samples from electrical contact properties, which very often also influence the non-ohmic behaviour, as reported previously for samples formed by metal-polymer-contacts (TOMOZAWA et al ;MIYAUCHI et al 1987MIYAUCHI et al , 1989.…”

We deal with optical properties of TTF-DT,NF together with electrical conductivity measurements made with rod-like samples carrying a silver paint contact at both ends. Schottky barrier formation was observed in each case, although strongly modified by tunneling carriers across the only thin barriers formed due to a high impurity content of the samples. In the higher voltage range non-ohmic bulk conductivity behaviour is manifest.

“…Presently, the metal/organic semiconductors interfaces have gained more attention in modern electronic technology [9]. The electrical properties of metal/organic semiconductors heterojunctions can be fabricated in the form of bulk and thin films by employing various materials [10,11]. These junctions play a vital role in the development of many devices like Organic Photovoltaics (OPVs), Organic Light-Emitting Diodes, Organic Field-Effect Transistors, lasers and memory devices [12][13][14][15].…”

Modern organic electronic and power electronic devices gained attention due their superior performance and efficiency with reduced cost. While nanocomposites of these organic semiconductors have high potential to further enhance these properties. In this work, thin films of zinc oxidepolyaniline (ZnO-PANI) nanocomposite with different compositions of ZnO (50, 60 and 70 wt%) are deposited by spin coater onto the surface of p-Si. The phase identification of the samples is identified through x-ray diffraction analysis. Pure ZnO showed wurtzite crystalline while PANI and nanocomposites of ZnO-PANI showed amorphous structure. The optical absorption band gap was evaluated from Ultraviolet-visible spectroscopy absorption studies and band gaps were calculated from Tauc's plots. The Ultraviolet-visible spectroscopy showed that by increasing ZnO content in the nanocomposite, the band gap increases from 3.25 eV to 3.3 eV and 3.4 eV for 50-50, 60-40 and 70-30 wt% respectively. The AC electrical properties of the nanocomposites were studied by using impedance spectroscopy. The parameters extracted from the impedance plots and conductivity values showed that 50-50 wt% is more conductive while that of 70%-30% wt is more resistive.

“…It is evident from numerous publications on polypyrrole family of polymers, that it is one of the promising materials for device applications. Several reports are available on Indium-polyprrole (In-PPY) junctions [2][3][4][5] and almost all the workers have tried to explain the results on the basis of Richardson's equation of thermionic emission. Unfortunately, the charge transport mechanism has not been discussed in girth, in any of these reports.…”

Samples of polypyrrole, poly(N-methyl pyrrole) and their copolymer poly(Nmethyl pyrrole-pyrrole) have been prepared by electrochemical polymerization technique. Their conductivity values have been optimized for fabricating indium-polymer Schottky junctions. The current-voltage characteristics of the indium-polymer Schottky junctions have been investigated. The results have been explained on the basis of thermionic emission theory.
