Dear all, I would like to artificially use 4 types of Silicon atoms, they are actually the same , and I used different types just to distinguish them in different groups.
Can I use following potential setting commands:
pair_coeff * * Si.tersoff Si Si Si Si
or I just replace C in SiC.tersoff by Si and copy “Si Si Si” lines 7 times. Thus, SiC.tersoff file will include 8 lines of “Si Si Si” parameters.
Then I use following commands.
pair_coeff * * SiC.tersoff Si Si Si C
Thanks and happy new year.
