(a) The schematic of conventional bilayer atomic model of (111) Al/(111) TiN with N termination at the interface. (b) The γ surface computed for strain-free bulk Al, for (11
) plane with displacements along [112] and [1
0], respectively. (c) The γ surface computed for Al strained: the Al lattice parameter is stretched to match that of TiN at the interface, for (11
) plane with displacements along [112] and [1
0], respectively. (d) The γ surface computed for Al1-Al2 planes at the Al/TiN interface in (a), with displacements along [112] and [1
0], respectively. Units are in mJ/m2 in (b–d).
