Molecular dynamics calculation of surface tension of liquid metals using the embedded atom model

Surface tension of liquid lithium, iron, gallium, and lead was calculated by the molecular dynamics method using embedded atom model (EAM) potential. Surfaces were formed by division of the molecular dynamics model in basic cube into two parts by applying the external field. Calculated surface tensions for liquid iron at 1820 K, gallium at 323 K, lithium at 463 K, and lead at 613 K were 1396, 633, 476, and 308 mJ/m2 correspondingly. Deviation of calculated values from experimental data was 1-32%.
