The effect of technological condition on electrical properties of ITO films Shengnan Zeng,Jiaxiang Liu* and Nan Zhang The State Key Laboratory of Chemical Resource Engineering, College of Materials Science and Engineering, Beijing University of Chemical Technology, Beijing 100029, People's Republic of China ljxpost@263.net Keywords: optimizing formation condition; electrical properties; ITO thin film Abstract: The transparent ITO multi-layers films were fabricated on quartz glass substrate by colloid dip-coating technique from indium metal ingots and stannic chloride.
From the results of research, it can be seen that the multi-layer films has optimum characteristics, whose sheet resistance is 117Ω/□, when the use level of Sn is 10%wt,heated in 800℃ 15min with repeated dip-coating seven times.. 1.Introduction Thin films of indium oxide doped with tin (ITO) are advanced ceramic material with high transmission in the visible region and a low resistivity.
Experimental Indium ingot of 99.99% purity and stannic chloride were used as the starting material.
