Three_Body_Stillinger_Weber_Zhang_Silicene_Model1_Si__MO_800412945727_002

Title
A single sentence description.
A three-body Stillinger-Weber (SW) Model (Parameterization) for Silicon Optimized for Silicene
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.
This is the Zhang et al. (2014) Stillinger-Weber potential optimized to reproduce properties of silicene (single-layer Si sheet) based on the KIM Model Driver Three_Body_Stillinger_Weber. The authors provide two sets of parameters. This parameterization corresponds to the parameter set referred to as "Optimized SW1" in Zhang et al. (2014). This version update is to make this model compatible with the model driver update to support multiple species. The functional form of the SW potential is written and there is a redifinition of parameters (e.g. A := A*epsilon). Besides, costheta_0 is updated from -0.3333333 to -0.3333333333333333 to give a better approximation of -1/3.
Species
The supported atomic species.
Si
Disclaimer

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. 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.

FCC Lattice Constant

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