The linear and nonlinear intra-band optical absorption coefficients in GaAs/Ga 1− x Al x As
two-dimensional concentric double quantum rings are investigated. Taking into account the …

The linear and nonlinear optical absorption associated with the transition between 1s and 2s
states corresponding to the electron-donor-impurity complex in GaAs/Ga 1− x Al x As three …

The rendering of different shapes of just a single sample of a concentric double quantum
ring is demonstrated realizable with a terahertz laser field, that in turn, allows the …

The effects of the magnetic field (γ), the radial position of impurity and the degree of
confinement on the oscillator strength (OS), refractive index and optical absorption (α) of an …

Here we address a theoretical analysis of the effects of applied hydrostatic pressure on
electron states in concentric GaAs–(Ga, Al) As double quantum rings, under axial magnetic …

We theoretically investigated the effect of the geometry change on the electronic and
magneto-optical absorption spectra of GaAs/Ga0. 7Al0. 3As double quantum rings. The …

The features of electron-donor-impurity energy spectrum and related optical response in
GaAs-AlGaAs concentric double quantum rings are investigated. The geometrical shape of …

Here we address a theoretical study of concentric GaAs–(Ga, Al) As double quantum rings,
under a magnetic field applied perpendicularly to the ring plane. Electron–hole transition …

We consider the effects of hydrostatic pressure, temperature, aluminum concentration and
impurity position on hydrogen-like donor binding energy in GaAs/Ga1− xAlxAs concentric …

The possibility of tailoring III-V GaAs/Al 0.3 Ga 0.7 As concentric double quantum rings
(CDQRs) by tuning the central barrier, width, and height of the rings brings out carrier …
