Abstract

Pressure  dependence  of  Raman-active  mode frequencies and linewidths in Cu3NbS4 ternary compound has been investigated up to 30 Kb (at room temperature) using focalized micro-Raman technique in a diamond anvil high pressure cell. Seven Raman-active modes frequencies were clearly observed in the pressure range studied and the variation of their respective  Raman  shift  frequency  as  a  function  of  pressure  were  given. A structural  phase  transition  at  25 ± 5 Kb previously reported in literature was confirmed.
