• The effect of substantial plasmon damping on the frequencies and damping rates of the coupled longitudinal optical (LO) phonon-hole plasmon modes is examined by finding the complex roots of ε(ω) = 0. The zeroes of the dielectric function ε(ω) give the frequencies of the longitudinal modes. The calculated results describe the anomalous downward shift and the single-mode behavior that we have observed previously for Raman spectra of the coupled modes in p-type GaAs.
