I was trying to simulate a Si-Ge interface for some MD modeling. The potential chosen was Tersoff-SiGe-1989. There was a message saying that the EMT calculator has no parameters for Ge. What does this mean? How may that affect my simulation? Is there a way around? I was trying to find the interfacial thermal resistance between Si and Ge, and was following the methodology described in the VNL tutorials for interface between Si(100) and Si(110).
