The impurity-anharmonicity interactions, along with anharmonicities, mass and force constant changes have been taken into account to investigate the expressions for microwave attenuation in anharmonic crystals. A remarkable change in the phonon frequency shifts and widths has been reported due to the defect anharmonicity interactions. The usual method of central and non-central force constant parameters has been ignored here and parameter free expressions have been reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
