Divacancy Binding Energy, Formation Energy and Surface Energy of bcc Alkali Metals Using MEAM Potential

The Modified Embedded Atom Method (MEAM) potential parameters have been employed to calculate the unrelaxed divacancy formation energy, binding energy, and surface energies for low-index planes in body-centered cubic (bcc) alkali metals. The calculated divacancy binding energies and vacancy formation energies show good agreement with experimental data and other available computational results.
