Abstract
The solid solubility of gold in germanium is determined in the temperature range between 500 and 870°C. Thin layers of germanium crystal saturated with gold at a desired temperature are prepared by the alloying process. The solid solubility is obtained through the measurement of sheet resistance or junction capacitance. The distribution coefficient of gold between the solid and liquid germanium is calculated with the aid of the available liquidus curve. The distribution coefficient shows a bend in its logarithmic plot against the reciprocal absolute temperature. The activation energy at higher temperatures is estimated to be (2.3±0.6) eV, which is close to the value, 1.65 eV, expected from Hall's theory.Keywords
