Nonlinear optical absorption in parabolic quantum well via two-photon absorption process

Magneto-optical transport properties of monolayer MoS2 on polar substrates

“…The main trend that can be observed here is that with increasing magnetic field the resonant peaks shift to higher energies and their amplitudes increase. This behavior of the MOAC is similar to that in a semiconductor quantum well [79] and in graphene [44,45,62]. This can be qualitatively explained in the one-particle picture as originating from the LL spectrum as follows: With the increase of the magnetic field, the LL spacing increases giving upswing to a higher energy of the absorbed photon.…”

Nonlinear optical absorption via two-photon process in asymmetrical Gaussian potential quantum wells

“…GaAs and Ga 0.7 Al 0.3 As quantum wells, as well as in the one-and two-photon absorption processes. The present result is in good agreement with the results of previous papers [33,34,[39][40][41][42][43]. This increase behavior of the half-width is explained from the increase of the probability of electron−phonon interaction when magnetic field increases.…”

Comparison of electron scattering by acoustic-phonons in two types of quantum wells with GaAs and GaN materials

“…In the case of this potential, the term U P ( z ) is revealed by 47–50 U P ( z ) = m *( ω P z ) 2 z 2 /2,where m * and ω P z are symbols of the effective mass of the charge-carrier and the characteristic confining frequency of the parabolic-well electron. In this case, the eigenfunctions ( χ P ( z )) and the corresponding eigenvalues ( E P n , ) of the parabolic-well electron are given byandwhere the Hermite polynomials of order are symbolized by H ( z / λ z ), = 0, 1, 2, …, and λ z = ( ℏ /( m * ω P z )) 1/2 .…”
