RAMAN CHARACTERIZATIONS OF RUTHENIUM DICHALCOGENIDES

Abstract

Raman scattering of single-crystal RuTe2 has been carried out with good frequency resolution and wide wavelength coverage. In this article, our results are presented and compared with those for other ruthenium dichalcogenides (RuSe2, and RuS2) reported previously. We found a good linear relationship between all Raman shifts and the reciprocal chalcogen mass. We also observed resonant scattering related to inter-electronic-band transitions.
