Abstract
The intrinsic stacking fault energies of diamond, germanium and grey tin have been calculated by the pseudopotential method to a second order perturbation approximation. The calculated value for germanium, 26 erg/cm2, falls within 50% of the experimental value determined by the weak-beam technique in electron microscopy. The value for diamond, questionable because of possible poor convergence of the method, is very large, 1860 erg/cm2. Grey tin exhibits a small value, 3 erg/cm2, which could in principle be easily measured experimentally.Keywords
