Title
A single sentence description.
MEAM potential for BeO structure developed by Wei et al. (2019) v001
Description
A short description of the Model describing its key features including for example: type of model (pair potential, 3-body potential, EAM, etc.), modeled species (Ac, Ag, ..., Zr), intended purpose, origin, and so on.
Modified embedded atom method potential parameters of beryllium oxide (BeO) have been developed, which can reproduce the thermodynamic properties of beryllium oxide. To accurately describe the interactions between the atoms in the BeO structure, the density functional theory is used to calculate the fundamental properties such as the lattice constant, bulk modulus, and elastic constants, which are used for the potential fitting. The properties such as the enthalpy and specific heat are used to test the potential parameters' validity. The developed potential parameters' calculated results are compared with the experimental and other theoretical data as a function of temperature. The good agreement between the calculated results by the new potential and the experimental data verifies the potential parameters. The developed potential parameters have also been used to predict the thermal conductivity of BeO as a function of temperature for further applications of beryllium oxide.

BCC Lattice Constant

This bar chart plot shows the mono-atomic body-centered cubic (bcc) lattice constant predicted by the current model (shown in the unique color) compared with the predictions for all other models in the OpenKIM Repository that support the species. The vertical bars show the average and standard deviation (one sigma) bounds for all model predictions. Graphs are generated for each species supported by the model.

Cohesive Energy Graph

This graph shows the cohesive energy versus volume-per-atom for the current mode for four mono-atomic cubic phases (body-centered cubic (bcc), face-centered cubic (fcc), simple cubic (sc), and diamond). The curve with the lowest minimum is the ground state of the crystal if stable. (The crystal structure is enforced in these calculations, so the phase may not be stable.) Graphs are generated for each species supported by the model.

Diamond Lattice Constant

This bar chart plot shows the mono-atomic face-centered diamond lattice constant predicted by the current model (shown in the unique color) compared with the predictions for all other models in the OpenKIM Repository that support the species.
