我们将这 21 个声子模式分为两类18 个极性可以忽略的声子模式(即极性为零或非常弱的声子),在拉曼散射过程中它们的电极性造成的效应可以忽略;
3 个强极性声子模式,在拉曼光谱中电极性效应是可观测的。
At each such position near the #sym.Gamma point,
there exist 21 phonon modes (with degeneracies counted accordingly).
At each position near the #sym.Gamma point,
there are 21 phonon modes (counting degeneracies).
These modes were categorized into two groups according to their electrical polarities:
18 negligible-polar phonons (i.e., zero or very weak electrical polarity),
in which same species atoms vibrate in opposite directions and the electrical cancellated with each other,
leading to negligible electrical polarity during Raman scattering process,
shown as gray lines in @figure-discont;
where atoms of the same species vibrate in opposite directions
resulting in effective cancellation of electrical polarization during the Raman process
(gray lines in @figure-discont);
and three strong-polar phonons,
in which all atoms of the same species vibrate in the same direction,
resulting in a strong dipole moment and observable electrical polarity in Raman spectra,
shown as colored lines in @figure-discont.
where atoms of the same species vibrate in phase,
resulting in strong electrical polarization and observable effects in Raman spectra,
(colored lines in @figure-discont).
