We measure the effects of phonon confinement on the Raman spectra of silicon nanowires. We show how previous spectra were inconsistent with phonon confinement, but were due to intense local heating caused by the laser. This is peculiar to nanostructures, and would require orders of magnitude more...
SWNT2). The integrated peak intensities for both nanotubes are plotted in Figure 6c as a function of AFM deflection voltage. We often observe a small, finite, broad peak intensity for zero force applied to the silicon cantilever, which then disappears for low values of strain (up to ca. 1...
Silicon nanowires synthesized on an amorphous substrate by the vapor-liquid-solid method were studied using Raman spectroscopy andab initiocalculations. The authors show that the Raman spectrum of Si nanowires is compatible with the existence of two distinct phases. The Raman spectra revealed a peak ...
signal. Low-order polynomial terms are used to account for small drifts of the background signal. In this work,mvaries from 0 to 2. Since the experiment was carried out on a silicon dioxide substrate, the silicon dioxide Raman spectrum was also included as a reference in the fitting process...
on the PCNA substrate are well distinguishable and consistent with those of the ground truth (with small differences which may be attributed to the different adsorption orientations of the biomolecules on the silicon and PCNA substrates5), which is verified by our peak assignment (Supplementary Fig...

7). The intensity of the SERS peak at 1002 cm−1 was plotted against the logarithm of the microplastic concentration. Fig. 7 shows that in the range of 0.05–100 mg mL−1 of microplastics, the linear correlations obtained had R2 = 0.9979, 0.9991, 0.9974, and 0.9943, for seawater, ...
