Sentence examples for peak downshift from inspiring English sources

In situ Raman and XRD measurements during tensile deformation indicate that the transfer of stress between bundles in the fibre is not uniform, with the Raman peak downshift rates for the D, G and G′ bands varying by as much as a factor of 2 in different areas of the fibre.

This exponential dependence with increasing dosage in both the C 1 s relative area and the peak downshift can have different explanations.

The doping behavior was further verified by Raman spectroscopy G-band peak downshifts.

When forming Lewis adducts, the C=O peaks separately downshift to 1658 and 1668 cm−1.

According to previous work [35 37, 39], the upshifting of G peak and the downshifting of 2D peak is caused by n-doping, as the silver nanoparticles were depositing on the graphene.

It is obvious that both G peaks and E2ghigh peaks show a progressive downshift as the temperature increases.

The slopes of p2 and p3 peaks also appeared to be close to the dispersion of single-layer graphene 2D band, with average frequency downshift for p2 peak about 36 cm−1 and the upshift for p3 peak about 26 cm−1.

From the obtained dispersion behavior of SWCNT 2D band and taking into account the energy of 2D band, which in our case makes ~0.3 eV, the expected downshift of p2 peak frequency position with respect to p1 peak in the considered double-resonant process can be estimated as ~30 cm−1 [10], which is close to experimentally observed downshift for peak p2.

The nature of less intensive downshifted p2 peak can be related to the processes of output resonances with vHSs (Fig. 3a, c).

Interestingly, it can be noted that a small downshift of C=C peak is observed in BDMT/G as compared to pristine CVD-grown graphene.

Theoretically, an increase in temperature can induce both line-width broadening and frequency downshift of phonon peaks.
