Abstract

The effect of the electron–LO-phonon interaction on the third-harmonic generation (THG) coefficient for cylinder quantum dots with an applied electric field is theoretically investigated, the THG coefficient is obtained by using compact-density-matrix approach and iterative method, and the numerical results are presented for a GaAs cylinder quantum dots. The results show that the THG coefficient is greatly enhanced and the peak shift to the aspect of high energy when considering the influence of electron–LO-phonon interaction.
