1The second harmonic generation in GaAs/GaAlAs spherical quantum dots under Woods-Saxon plus attractive inversely quadratic potential显示文摘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.Xuechao Li Yiming Duan Yongrui Ma 2022Communications in Theoretical Physics2022,74,8:0
2Spherical quantum dot in modified Kratzer-Coulomb potential:study of optical rectification coefficients显示文摘We consider the effects of quantum dot radius,confinement potential depth and controllable effective mass on the optical rectification coefficient(ORC)in spherical quantum dots,which is confined with Modified Kratzer-Coulomb Potential(MKCP).Using the Nikiforov-Uvarov method and compact density matrix theory,the ground state energy,ORC and wave function of electrons under the combined action of many factors are calculated.The results show that they affect the optical rectification response from different angles,including the position of peak and formant.Xuechao Li Ceng Chang Yongrui Ma 2022Communications in Theoretical Physics2022,74,6:0
