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

Liquid phase epitaxial growth of AlGaSb
TL;DR: In this paper, the authors investigated the optimum conditions for the liquid phase epitaxial growth of AlGaSb and for the heat treatment of substrates, finding that high-temperature heat treatment prior to growth can damage the surface of the substrates resulting in poor interfacial properties and formation of Ga inclusions.

Coherent, nonlinear two-phonon Raman spectra of diamond
G. L. Eesley,Marc D. Levenson +1 more
TL;DR: This is the first reported observation of a second-order Raman spectrum by means of coherent Raman spectroscopy, and the frequency of the sharp two-phonon peak was measured to be 2668.6 +/- 0.5 cm(-1), in agreement with lower-resolution spontaneous-scattering measurements.

The role of atomic vacancies on phonon confinement in α-GeTe
Geetanjali Kalra,Sevi Murugavel +1 more
TL;DR: In this paper, XRD and Raman spectroscopy on α-GeTe single crystal with different sizes are reported to reveal the evolution of phonon confinement with crystal sizes of few hundred nanometers, and the characteristic vibrational modes of bulk αGeTe structure are found to downshift and asymmetrically broaden to lower frequency with decreasing the single crystal size.

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.
