Fig. 1. Schematic illustration of typical slip planes and directions in a HCP unit cell (a). Schematic view of the initial and shifted supercell used to calculate the SFE for various slip systems: (b) {0001} <11-20> and (c) {10-10} <11-20> systems, respectively. The red line represents the slipping plane. A vacuum width of 15 ? was added to avoid the interaction due to periodic images.
