Citrate-stabilized palladium nanoparticles as catalysts for sub-20 nm epitaxial silicon nanowires.
Appl. Phys. Lett. 97 (2010), 023105

Citrate-stabilized palladium nanoparticles with a mean diameter of 13 nm were synthesized in aqueous solution. These particles were utilized as catalysts to grow epitaxial silicon nanowires by chemical vapor deposition at temperatures below 500 °C. The resulting nanowires have a mean diameter of 15 nm. It is found that during the growth process the palladium particles transform into dipalladium silicide.
