A simple scheme was used to calculate the energies of stacking faults, polytypes and arbitrary stacking sequences in elementary and compound semiconductors. The scheme was based upon the calculation of two elementary energies which could be obtained, for each material, from the computed difference in energy between its cubic and hexagonal modifications and from the measured or computed energy of a single kind of stacking fault. Formulae were given for faults in both zincblende and wurtzite structures, and for the stacking sequences that occurred during the transformation of one phase into the other. This was particularly applicable to nanowires, where such faults and sequences were frequently encountered.
