Pressure measurements of TO-phonon anharmonicity in isotopic ZnS

Abstract:

We have measured the dependence on pressure of the line-widths of the TO and LO Raman phonons of β-ZnS. In order to enhance the phenomena observed, and to eliminate possible effects of isotopic disorder, we have measured a nearly isotopically pure crystal, 68Zn32S. The strongly structured pressure effects observed are interpreted on the basis of anharmonic decay and the corresponding two-phonon density of states. © 2004 WILEY-VCH Verlag GmbH & Co.
