Germanium current voltage characteristics

The data of Efimov and Erusalimchik (5) shown in Fig.l give an example of the different current-voltage characteristics obtained with various resistivity n- and p-type germanium electrodes made anode in 0.1 N HC1. Brattain and Garrett (4) and others (7-10), however, found much lower saturation current densities by one to two orders of magnitude with n-type germanium made anode in similar electrolytes. Similar curves for n-type silicon would show saturation current densities in the order of microamperes per square centimeter.
