Infrared and Raman Investigations of Long-Wavelength Phonons in Layered Materials

Chapter
Part of the Physics and Chemistry of Materials with Layered Structures book series (PCMA, volume 3)

Abstract

Research interest in the phonon energies of layered crystal structures has grown rapidly during the last decade. The reasons for the interest vary from fundamental considerations concerning low-dimensional systems to the utility of these materials as superconductors, lubricants, and thermoelectric elements. Infrared and Raman studies of layered materials were initiated long before the current phase of research activity. The first infrared spectrum was obtained on brucite [Mg(OH)2] in 1905 by Coblentz [1]; however, relatively few papers were reported in the literature before 1960. Krishnamurti’s work [2] on Mg(OH)2 and Ca(OH)2 appears to have been the first extensive Raman study of layered compounds. Current activity has also greatly benefited from instrumental developments in spectrometers and laser light sources. Infrared and Raman techniques are now mature, and they have been used to advantage in far-infrared and high-resolution work on layered structures. (The former experimental difficulties can be appreciated by reading the survey of the Raman effect in solids by Menzies [3], which was written a little over twenty years ago.)
