WebJan 15, 2024 · A basic approach considers the atomic density on each crystallographic plane, the number of bonds broken if the surface is cleaved along that plane and combines these two. Is this a realistic and reasonable approach if I want to compare the surface energies of two crystallographic planes, say (100) and (111)?
