| 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 Ge configurations |

| Configuration Sets by Name |
Ge_ground — Ground state structure Ge_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. Ge_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. Ge_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. Ge_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 |
