Thin NiTi Films Deposited on Graphene Substrates (bibtex)

by S. Hahn, A. Schulze, M. Böhme, T. Hahn, M. F.-X. Wagner

Abstract:

We present experimental results on the deposition of Nickel Titanium (NiTi) films on graphene substrates using a PVD magnetron sputter process. Characterization of the 2–4 micron thick NiTi films by electron microscopy, electron backscatter diffraction, and transmission electron microscopy shows that grain size and orientation of the thin NiTi films strongly depend on the type of combination of graphene and copper layers below. Our experimental findings are supported by density functional theory calculations: a theoretical estimation of the binding energies of different NiTi–graphene interfaces is in line with the experimentally determined microstructural features of the functional NiTi top layer.
