Web2 days ago · Alexander A. Balandin is an electrical engineer, solid-state physicist, and materials scientist best known for the experimental discovery of unique thermal properties of graphene and their theoretical explanation; studies of phonons in nanostructures and low-dimensional materials, which led to the development of the field of phonon engineering; … Raman scattering or the Raman effect is the inelastic scattering of photons by matter, meaning that there is both an exchange of energy and a change in the light's direction. Typically this effect involves vibrational energy being gained by a molecule as incident photons from a visible laser are shifted to … See more The elastic light scattering phenomena called Rayleigh scattering, in which light retains its energy, was described in the 19th century. The intensity of Rayleigh scattering is about 10 to 10 compared to the intensity of the … See more The Raman-scattering process as described above takes place spontaneously; i.e., in random time intervals, one of the … See more Raman spectroscopy employs the Raman effect for substances analysis.
