Abstract
A review is given of progress in the theoretical and experimental study of the Raman effect in crystals during the past ten years. Attention is given to the theory of those properties of long-wavelength lattice vibrations in both cubic and uniaxial crystals which can be studied by Raman scattering. In particular the phenomena observed in the Raman scattering from crystals which lack a centre of inversion are related to the theory. The angular variations of the scattering by any type of lattice vibration in a crystal having any symmetry can be easily calculated using a complete tabulation of the Raman tensor. Recent measurements of first-order lattice vibration spectra are listed. A discussion of Brillouin scattering is included. The relation of second-order Raman spectra to critical points in the lattice vibration density of states is discussed, and measurements of the second-order spectra of diamond and the alkali halides are reviewed. The theory and experimental results for Raman scattering by electroni...

Breakdown of Raman Selection Rules By Fr\"{o}hlich Interaction in Few-Layer WS$_2$

TL;DR: In this paper, the authors reported the breakdown of Raman selection rules in few-layer WS$_2$ by using resonant Raman scattering with dark A exciton.

On the Raman Intensities of Polycrystalline Samples

TL;DR: The measurement of Raman intensities, absolute or relative, in the solid state has been hitherto seldom accomplished as discussed by the authors, which is surprising because they supply valuable information for the study of solid state structure and because for polycrystalline samples, there are no serious experimental difficulties in the measurement of relative intensities.

Dynamic characterization of MEMS using Raman spectroscopy

TL;DR: In this paper, the authors used Raman spectroscopy to characterize the motion and measure strain levels in dynamic micromechanical structures and obtained a measurement resolution of 210 µstrain at frequencies up to 100 kHz.

Breathing modes in few-layer MoTe 2 activated by h-BN encapsulation

TL;DR: In this paper, the authors investigated low-energy Raman scattering spectra of bi-and trilayer MoTe2 and found that three breathing modes are observed in the Raman spectra.

Dynamical Theory of Crystal Lattices

Max Born, +1 more
TL;DR: Born and Huang's classic work on the dynamics of crystal lattices was published over thirty years ago, and it remains the definitive treatment of the subject as mentioned in this paper. But it is not the most complete work on crystal lattice dynamics.
