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...read more

Study of structural, optical and magnetic properties of cobalt doped ZnO nanorods
TL;DR: In this article, a micro-Raman study of Co-doped zinc oxide nanostructures indicates the incorporation of Co in ZnO and the observed ferromagnetism may have originated due to the exchange interaction between the localized d electrons in Co2+ atoms and free carriers generated due to Co doping.

TL;DR: Growing µm-sized SnS monolayers that exhibit in-plane ferroelectricity that is stable at room temperature is demonstrated, paving the way for nanoscale ferro electric applications based on SnS as a platform for in- plane ferroelectrics.
Raman and Infrared Spectral Studies of Anhydrous Li2CO3 and Na2CO3
TL;DR: In this paper, the infrared and Raman spectra of anhydrous crystalline Li2CO3 and Na2Co3 were measured at 300 and 80°K, respectively, and it was shown from these measurements that the infrared transmission spectra exhibited band maxima which are admixtures of LO and TO modes.

Dynamical Theory of Crystal Lattices
Max Born,Kʿun Huang +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.
