Self-Diffusion in Germanium

Abstract

An accurate determination of the self-diffusion coefficient in germanium has been obtained. In the temperature range 766-928°C, it is represented by $D=7.8\mathrm{}\exp (-\frac{68500}{\mathrm{RT}})$ ${\mathrm{cm}}^2$ sec. The probable errors in the frequency factor and activation energy are ±3.4 ${\mathrm{cm}}^2$/sec and ±0.96 kcal/mol, respectively.
