Abstract
The dissolution of single‐crystal germanium has been studied in electrolyte solutions containing dissolved oxygen. The following electrolytes were considered: , , , , , , , , and . In the range 10−6 to 1.0N, the dissolution rate typically goes through a maximum as the electrolyte concentration is increased. The concentration corresponding to maximum dissolution rate is different for the various electrolytes but, in general, is less than 10−2 N. In the case of , two distinct maxima were observed; in solutions the maximum is followed by a minimum. The activation energy for the reaction in O2‐saturated solutions was found to be about 19 kcal/mole. At very low oxygen partial pressures, the activation energy was less than 5 kcal/mole, indicative of diffusion‐controlled kinetics.Keywords
