Electrical Conductivity of Tetrathiafulvalene‐9‐Dicyanomethylene‐2,4,5,7‐tetranitrofluorene(TTF‐DT₄‐NF)

Abstract

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.

Hygrothermal Stability of Electrical Contacts Made from Silver and Graphite Electrically Conductive Pastes

“…3 The hygrothermal stability has not been addressed. This paper is aimed at comparative evaluation of the electrical durability (hygrothermal stability) of electrical contacts made by using various conductive pastes, including (1) silver paint, [6][7][8] (2) silver paint with a nonconductive epoxy protective over- coat (a case that has not been previously reported), (3) silver epoxy, 4,[9][10][11] and (4) graphite colloid (colloidal graphite, also known as Aquadag, which is originally a trademark of Acheson Colloids Company, Port Huron, MI, and is most widely used as a coating in cathode-ray tubes). [12][13][14] The durability evaluation in this work involves exposure to elevated temperatures and water, because heat and moisture are commonly encountered in practical use environments.…”
