Tersoff ZBL

The Tersoff/ZBL potential says that the Tersoff potential used is the one from 1988 (this is found on doc page). However, the 1988 paper is parameterized only for silicon unless I am mistaken. Tersoff published a paper in 1989 for Si, C.

Is this what was meant? I am confused on how the Tersoff potential from 1988 is used when the paper did not provide data for C.


Tersoff/ZBL uses the “form” given in the 1988 paper, but many different “parameterizations” can use the same “form”. It is clear that Tersoff/ZBL’s form is given in the 1988 paper and Si-C paramters are given in the other 1989 paper.


Ok, thanks for clearing that up!
