ABSTRACT
We have measured the electrical properties of self-assembled epitaxial NiSi2 nanowires (NWs) formed on Si substrates. We find quantum corrections due to weak antilocalization and electron–electron interactions. Analysis of the magnetoresistance indicates that electron phase coherence in the NWs is limited by Nyquist dephasing below 10 K, and by electron–phonon scattering at higher temperatures. The phase-breaking and spin–orbit scattering lengths are found to be ∼45 nm and 3–7 nm, at 4.2 K, respectively, similar to reports for thin NiSi2 films.

    Since the formation of epitaxial silicide nanowires by deposition of rare earth (RE) metals on Si(001) was first discovered, intense interest has been focused on their growth mechanism. Unlike many of the other nanowire forming RE metals, which have several different polymorphic silicides at...
