, Germany 10.3762/bjnano.11.99 Abstract Tip-enhanced Raman spectroscopy is combined with polarizationangle-resolvedspectroscopy to investigate the nanometer-scale structural properties of core–shell silicon nanowires (crystalline Si core and amorphous Si shell), which were synthesized by platinum
local structural properties of Si nanomaterials at the sub-10 nanometer scale using tip-enhanced Raman techniques.
Keywords: core–shell nanowires; local crystallinity; polarizationangle-resolvedspectroscopy; silicon; tip-enhanced Raman spectroscopy; Introduction
The properties of silicon are long
nanocrystalline, depending on the synthesis parameters. Hence, these nanowires resemble ideal objects to study local crystallinity variations at the sub-10 nanometer scale using TERS. Furthermore, polarizationangle-resolvedspectroscopy is for the first time combined with TERS, in order to reveal the different
