Resonance enhancement of E’’(2) mode has been observed for both incident and scattered photon energies equal to the free-to-bound transition energy.EnglishGaSeLayered crystalsSemiconductor compoundsElectron transitionsHelium neon lasersPhotonsRaman scatteringResonanceSpectrum analysisSynthesis (chemical)Resonant Raman scattering (RRS)PolycrystalsResonant Raman scattering near the free-to-bound transition in undoped p-GaSeArticle10.1002/1521-4079(200112)36:12<1393
