Crystalline silicon (Si) nanowire could be directly grown from Si wafer upon thermal annealing in the presence of catalyst such as gold (Au). However, the role of the catalyst layer thickness is yet elucidated. In this work, 10 nm, 20 nm, and 40 nm Au layers were respectively sputtered on Si wafer s...
