Calculation of stacking-fault energy of polytypic structure

Abstract
A method of calculation of stacking-fault energy for polytypic structures has been developed. The method is based on the Hirth and Lothe procedure for fcc and bcc structures. The case of calculation of stacking-fault energy for cadmium iodide polytypic structures has been specifically dealt with. The applicability of the method to polytypic structures of other substances as well as to metallic and alloy phase structures has also been outlined.
