Elastic Properties of Nickel Carbides — •Jeffrey Kelling1,2, Peter Zahn2, and Sibylle Gemming1,2 — 1Institute of Physics, TU Chemnitz, Chemnitz, Germany — 2Institute of Ion Beam Physics and Materials Research, Helmholtz-Zentrum Dresden-Rossendorf, Dresden, Germany
The nickel – carbon system has received increased attention over the past years due to the relevance of nickel as a catalyst for carbon nanotube growth and as a substrate for metal-induced crystallization of graphene and graphite. Nickel carbides as bulk materials are out of reach for experimental studies because of their meta-stability. Ab-initio studies are rare. We present our ab-initio – frozen phonon results for the elastic properties of Ni3C, Ni2C and NiC.
