Raman studies of hg1-xcuxba2ca2cu3o8 + δcompounds

Abstract EN

Solid state reaction method by two steps was used to synthesize Hg1- xCuxBa2Ca2Cu3O8 + δ samples where x= 0.1and 0.5.

Comparative Raman studies of Cu-doped Hg1-xCuxBa2Ca2Cu3O8 + δ were presented in an attempt to clarify the phononic modifications induced by Cu substitution.

A number of phonon peaks showed up in the spectra assigned to different phases, usually small amounts of starting material that did not react or secondary products were unintentionally grown.

On other hand foreign phases have much larger Raman signals and showed up strongly in the spectra.
