Abstract:
A method of four-needle elect rodes in measuring metallic materials w as transplanted in this paper to elect roconduct ive f ilms. The uniformity of electrocondutive f ilms is lower than that of metals, but they can w ork under smaller electric current s. Research is done on the infinite-plane electroconduct ive f ilms and then on the tube electroconduct ive f ilms. The paper put forward an empirical formula about the resistance of electroconduct ive f ilms , extending the application of the method.
