of the Raman peaks of crystalline Si and amorphous Si by applying tip-enhanced Raman spectroscopy, at sample positions being 8 nm apart. The localcrystallinity revealed using confocal Raman spectroscopy and tip-enhanced Raman spectroscopy agrees well with the high-resolution transmission electron
local structural properties of Si nanomaterials at the sub-10 nanometer scale using tip-enhanced Raman techniques.

The properties of silicon are long
the optical and electronic behavior of nanowire building blocks. Hence, there is an inherent need for non-destructive characterization techniques that are able to elucidate the localcrystallinity.
Raman spectroscopy is such a type of non-destructive characterization techniques and has become a
