摘　　要：We examine the profile of second harmonic generation(SHG)for GaAs/GaAlAs spherical quantum dots(QDs)of Woods-Saxon(WS)plus attractive inversely quadratic(AIQ)potential under the joint influence of additional factors(pressure and temperature)and structural parameters(strengths and radius).The energies and wave functions in GaAs/GaAlAs spherical QDs under WS-AIQ limiting potential are calculated using the parametric Nikiforov-Uvarov(NU)method.Depending on the calculated energies and corresponding wave functions,the SHG coefficient is examined by the iterative procedure in the density matrix method for this system.Finally,the calculated results display that a strong SHG coefficient response,and red shift or blue shift energy can be acquired by adjusting parameters.
