Abstract

The electrical properties of self-assembled epitaxial NiSi 2 nanowires (NW) formed on Si substrates were measured. The quantum corrections due to weak antilocalization and electron-electron interactions were also found. The analysis of magnetoresistance indicates that electron phase coherence in the NWs was limited by Nyquist dephasing below 10 K. The phase-breaking and spin-orbit scattering lengths were found to be ∼45 nm and 3-7 nm, at 4.2 K, comparable to those in thin NiSi 2 films. The nanoscale dimensions of the NWs allow the observation of quantum transport at higher temperatures (at least 30 K).
