WebBond order potential. Potential energy per bond, illustrating of how the value of the bond order in a Tersoff-type potential shifts the potential energy minimum. Bond order potential is a class of empirical (analytical) interatomic potentials which is used in molecular dynamics and molecular statics simulations. WebFinnis–Sinclair (FS) potential developed by Wilson and Mendelev [3]. The systems studied in the simulations are given in Table 1. In order to avoid any surface effect, periodic boundary conditions are applied in all the direc-tions. Free solidiﬁcation approach [2] is adopted in mea-suring the interface velocity and sandwich method is used
