[14a-2S-1] The influence of hole distribution on interference
between LO phonon and inter valence band transition
Keywords:quantum interference,GaInP,Raman spectroscopy
The quantum interference between 2 LO phonon (discrete states) and inter valence band transition (continuum) is arisen on p-GaInP. In Raman spectra, asymmetric line shape and LO peak shift characterize quantum interference effect. It was found that the inverse of asymmetry and the direction of energy shift depend on carrier thermal distribution.
