Abstract:

 

Polaron effects on the second-harmonic generation (SHG) in asymmetrical semiexponential  quantum wells (ASEQWs) are  investigated theoretically. By using the framework of the compact-density-matrix approach and  iterative method, the analytical expression of the   SHG coefficients in ASEQWs is presented. Numerical results are  illustrated for a typical GaAs/AlGaAs. By  considering  the electron--LO--phonon interaction (ELOPI), the energy levels and the wave  functions of an electron confined in ASEQWs are obtained. It is found that whether we consider the ELOPI or not, the incident photon frequency ωω\omega and parameters U0U0U_0 and σσ\sigma also affect the SHG coefficient obviously.
