Description

Resonance effects are observed in the Raman cross-section of the defect chalcopyrite CdGa2Se4. The results indicate a strong resonance of the highest frequency E(LO) sphalerite-like phonons in forbidden geometry, similar to the behaviour observed for zincblende-like crystals. The forbidden scattering may be described through a Froehlich intraband mechanism at the fundamental direct gap. (author)
