Description A comprehensive DFT data set was generated for six elements - Li, Mo, Ni, Cu, Si, and Ge. These elements were chosen to span a variety of chemistries (main group metal, transition metal, and semiconductor), crystal structures (bcc, fcc, and diamond) and bonding types (metallic and covalent). This dataset comprises only the Si configurations

Configuration Sets by Name Si_vacancy — NVT AIMD simulations of the bulk supercells with a single vacancy performed at 300 K and 2.0x of the melting point of each element. The bulk supercells were heated from 0 K to the target temperatures and equilibrated for 20,000 time steps. A total of 40 snapshots were obtained from the subsequent production run of each AIMD simulation at an interval of 0.1 ps.
Si_AIMD_NVT — NVT ab initio molecular dynamics (AIMD) simulations of the bulk supercells performed at 300 K and 0.5x, 0.9x, 1.5x, and 2.0x of the melting point of each element with a time step of 2 fs. The bulk supercells were heated from 0 K to the target temperatures and equilibrated for 20 000 time steps. A total of 20 snapshots were obtained from the subsequent production run in each AIMD simulation at an interval of 0.1 ps.
Si_surface — Slab structures up to a maximum Miller index of three, including (100), (110), (111), (210), (211), (310), (311), (320), (321), (322), (331), and (332), as obtained from the Crystalium database.
Si_strain — Strained structures constructed by applying strains of -10% to 10% at 2% intervals to the bulk supercell in six different modes. The supercells used are the 3 x 3 x 3, 3 x 3 x 3, and 2 x 2 x 2 of the conventional bcc, fcc, and diamond unit cells, respectively
