Linear and nonlinear intersubband optical absorptions in an asymmetric rectangular quantum well

Computation of ionization and various excited state energies ofhelium and helium‐like quantum dots

“…The confined systems in all three dimensions are called quantum dots (QDs), which are often referred to as artificial atoms that show the properties of atoms such as discrete energy levels and shell structures [2,3]. Therefore, some authors have focused on the electronic structure, energy levels, binding energies, relativistic effects, optic properties, and other physical parameters of QDs by using various methods such as variational approach [4,5], perturbation [6,7], quantum genetic algorithm (QGA) and Hartree-Fock Roothaan (HFR) [8][9][10][11][12][13], exact solution [14,15], and other methods [16,17].…”

Intersubband and Interband Absorptions in Near-Surface Quantum Wells Under Intense Laser Field

“…Such an asymmetry in potential profile can be obtained either by applying an electric/laser field to a symmetric quantum well (QW) or by compositionally grading the QW. In these structures the changes in the absorption coefficients were theoretically predicted and experimentally confirmed to be larger than those occurred in conventional square QW (Karabulut et al, 2007;Miller, D.A.B. et al, 1986;Ozturk, 2010;Ozturk & Sökmen, 2010).…”

Built-in electric field effect on the linear and nonlinear intersubband optical absorptions in InGaN strained single quantum wells

“…It is worthwhile to point out that the linear absorption comes from the contribution of the linear susceptibility w ð1Þ term and the nonlinearity in the absorption coefficient is due to the third-order nonlinear susceptibility w ð3Þ term [20].…”
