- Abstract
- Vertically grown Si wire arrays were fabricated on a large scale by the Ni-catalyzed vapor-liquid-solid method. A single Si wire has a length of several tens of micrometers with a pure Si stem and a NiSi2 tip. The NiSi2 tip was spontaneously formed on a Si wire due to a slight lattice mismatch relative to Si. Further, this system provides a Schottky contact having a rectifying ratio of similar to 10(2) with a low leakage current of about 2.88 x 10(-10) A. The growth mechanism of vertical Si wires and the performance of a Schottky diode are discussed. (C) 2010 American Institute of Physics. [doi:10.1063/1.3467839]
