Abstract
Copper diffusion in germanium is fundamentally and technologically important as it has a very low activation energy and influences the precipitation and gettering of copper respectively These constitute the understanding of copper’s diffusion properties in germanium over a range of temperatures and pressures important In the present study we use the cBΩ model in which the defect Gibbs energy is proportional to the isothermal bulk modulus B and the mean volume per atom Ω The elastic and expansivity data is used in the description of the cBΩ model to derive the copper interstitial diffusion coefficient in germanium in the temperature range 827–1176 K The calculated results are discussed in view of the available experimental data
