Simultaneous effect of impurities, hydrostatic pressure, and applied potential on the optical absorptions in a GaAs field-effect transistor

Effect of Ring Radius and Electric Field on the Relative Refractive Index of a GaAs Quantum Ring

“…(2) will lead the energies of levels, E and the corresponding wave functions 𝜙(𝑥, 𝑦) and thereby the electronic spectrum of QR will be obtained. After the determination of the electronic structure of QR, the first order coefficient of relative refractive index changes can be calculated with the help of the density-matrix approach and the analytical expression for it is given as follows [27][28][29],…”

Spin–Orbit and Zeeman Effects on the Electronic Properties of Single Quantum Rings: Applied Magnetic Field and Topological Defects

“…Varying some of their compositional or configurational features-such as size and geometry-or applying external fields to them, their physical properties can be conveniently tuned. This allows for their use in various research fields such as electronics, optoelectronics, photonics, and sensing (see [1][2][3][4][5]). Within this realm, semiconductor quantum rings (QRs) are low-dimensional structures in which, according to a suitable design, the charge carriers can be confined to move in two dimensions.…”

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

“…The application of a magnetic field provides an additional parabolic confinement that causes further spatial spread in the wave functions so that affecting the dipole matrix elements. The influences of both electric and magnetic fields have been theoretically and experimentally studied by many researchers [11][12][13][14][15][16][17][18][19][20][21]. For instance, Dakhlaoui et al, investigated the effects of magnetic and electric fields on the TOAC [22].…”
