Abstract:We propose a bottom-up technique
using total wet chemical treatments
to separate neighboring terraces on Si(111). First, Ag cations were
reduced at the step edges of a vicinal Si(111) surface composed of
biatomic steps and flat terraces, resulting in self-assembled Ag rows
consisting of nanodots and nanowires. By immersing this sample into
a mixed solution of HF and H2O2, almost continuous
nanotrenches with depths and widths of nanometer scales were fabricated
along the edges. The potential electrochemical pro… Show more
