Abstract

We have measured the three independent components of the two-phonon Raman tensor of Si and GaP at room temperature. The component of Γ₁ symmetry is the strongest, while the Γ₁₂ component is practically negligible. The Γ₁ components are due mainly to overtone bands; the Γ₁₅ component observed in GaP seems due to combinations of the TO and LO branches: the Γ₂ spectrum of Si is essentially a replica of the density of states of the transverse optical phonons. The results are compared with neutron scattering data.
