“…5,7,18,28,[93][94][95] Different properties are used in literature to identify the atoms in the disordered region, such as the atomic potential energies, 4,7 the bond angles, 5 the ring structures, 15,28 the Lindemann spheres, 9,30 and the time-average of atomic positions. 10 The Wigner-Seitz defect analysis 84 has been widely used as well, 6,11,14,21 even though it is less suitable for amorphous structures. I use the atomic potential energy for simplicity, and atoms with potential energies greater than the crystalline average by 0.2 eV 4,7 are identified as disordered atoms.…”
