Electrical stress on transparent conductive oxide layer

Transparent conductive oxides (TCO) are a class of materials with good electrical conductivity and low visible light absorption. Their properties can be tuned by additional doping and by deposition techniques. In this way their applications are as active and passive electronic and opto-electronic devices. In this paper we present the electrical properties of an antimony doped tin oxide (ATO) layer deposited by screen printing techniques in a roll-to-roll process. We focus on the DC-and pulsed behavior of this conductive layer on flexible substrates and the resulting changes of his resistive properties under normal and stressed conditions.
