Electric and magnetic field effects on the optical absorption of elliptical quantum wire

Optical Properties of GaAs Nanowires with an Electric Potential That Varies Inversely with the Square of the Radial Distance

“…. Results for the ℎ 0 = 0 case concur with those in the literature [14,23]. As can be seen from the figure, the inverse parabolic potential redshifts peaks of the AC.…”

“…Optical properties of laterally coupled quantum wires were studied, which revealed that the linear and nonlinear absorption coefficients become blueshifted when the nanowires get closer to each other [12]. Other studies on optical properties of nanowires have shown that external magnetic field and electric fields modify absorption coefficient of the nanostructures [13,14]. Effect of a tilted electric field on optical absorption of quantum wires has also been reported on [15].…”

“…Absorption of the incident radiation is only possible if the energy of the radiation, ℎ , is coincident with the energy difference between different states between which transitions are possible. Firstorder and third-order absorption coefficient of a crystal can be evaluated by utilizing the density matrix approach in conjunction with perturbation expansion method via [11][12][13][14] (…”

Theoretical study of electronic and optical properties in doped quantum structures with Razavy confining potential: effects of external fields

“…Among these factors, we can cite the insertion of delta doped layers, as well as the application of either nonresonant intense laser field radiation, electric fields, magnetic fields, or a combination of these probe fields. All of them would play a crucial * Corresponding author (C. A. Duque): carlos.duque1@udea.edu.co role in tuning the energy spectrum of the confined carrier states [1][2][3][4][5][6][7][8][9][10].…”

“…The Eqs. (6)(7)(8)(9) are discretized using the finite difference method (FDM) and solved iteratively. Under such a procedure, the Schrödinger and Poisson equations are then changed to matrices of type A x = λ x and B x = ρ, respectively.…”
