Nonlinear optical rectification of hydrogenic impurity in a disk-like parabolic quantum dot: The role of applied magnetic field

“…Hence, the investigation of electronic and optical properties of hydrogenic impurities is essential to optimize the performance of the photoelectric devices. Many authors investigated the properties of hydrogenic impurities in SQDs [11][12][13][14][15][16][17][18][19]. In addition, external perturbation such as application of an electric and magnetic field can provide valuable information [20][21][22].…”

Additive Gaussian white noise modulated excitation kinetics of impurity doped quantum dots: Role of confinement sources

“…Under the confinement, the dopant location monitors the electronic and optical properties of the system [3]. This resulted in an abundance of literature comprising of theoretical studies on impurity states [4][5][6][7][8][9][10][11][12][13][14][15][16] in general, and also on their opto-electronic properties, in particular, for a wide range of semiconductor devices [3,[17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. In addition to these there are also some experimental works which encompass the mechanism and control of dopant incorporation [32][33][34][35].The highly practised research trend not only explores new physics but also indicates profound technological impact simultaneously.…”

Absorption spectra of a donor impurity in a quantum ring

“…Hence, a number of theoretical investigations of the hydrogenic donor in lowdimensional semiconductors have been published [8][9][10][11][12][13][14][15][16][17]. In the optical transition of quantum-confined few-electron systems, the analysis of the hydrogenic donor states is also inevitable because the confinement of quasiparticles in such structure leads to the enhancement of the oscillator strength of electron-impurity excitations.…”
