Sažetak
Current-voltage characteristic of the two phase sample of silver sulphide placed between indium contacts is measured and described within the frame of Wagner's theory of mixed (ionic and electronic) conduction. Electrical field applied in the - forward direction causes the formation of weak concentration gradients of moving particles, which at lower voltages leads to a linear characteristic. In the reverse biased cell the events are more complicated, including probably a partial decomposition of the sample and the formation of a highly resistive layer of indium sulphide. Characteristic in this case is exponential and similar to the characteristic of an electrolytic rectifier.
