Sentence examples for band peak from inspiring English sources

In graphene, the phonon energy shift caused by laser excitation creates three main peaks known as G band (peak: ~1580 cm−1), D band (peak: ~1350 cm−1), and 2D band (peak: ~2700 cm−1) [47].

A 2D band peak at 2,692 cm-1 and a G band peak at 1,580 cm-1 are shown.

During this phase, photoluminescence band peak position and photoluminescence band width remained constant.

Additionally, the PL band peak position is almost independent of Cr content.

A new Raman band peak was observed at 2276 cm−1 in PMMA-wrapped nanocomposites.

It can be seen that a strong G band peak at about 1594 cm−1 corresponds to graphitic structure, and a weak D band peak indicates a good quality of SWNTs.

At the same time, the G-band peak position Pg decreases while the sp3 fraction increases.

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