I have been trying to model ZrNiSn Half Heusler using the eam potential in LAMMPS MD package. For this I use a single eam potential file with the descriptions of all the species available in it. Also, I want to see the effect of the addition of Ti atoms on the thermal conductivity. However, the eam potential file which I have supports only Zr, Ni and Sn.
Even though I can find the eam potential for Ti on the internet, I am not sure about the ability of LAMMPS to model the Ti interactions with other species.
Can someone confirm whether it is possible to use such a separate file to model the Ti interactions. Would LAMMPS be supplied with the required data on the interactions of Ti with other species if this is done?
