Effects of hydrostatic pressure on the self-polarization in GaAs/Ga1−x Alx As quantum wells under the electric field

Self‐Polarization of Hydrogenic Impurity in Quantum Wells Made of Different Materials

“…[ 46 ] The E b and SP/e calculations obtained for the QW1 structure, which we consider as a reference, are in agreement with the literature. [ 5,17,25,34,44,45 ] In line with the calculations for the QW1 structure, we have calculated the binding energies and self‐polarizations for the QW2, QW3, and QW4 structures. The E b calculations are shown in Figure 1–3 and the SP/e calculations are shown in Figure 4–6 .…”

“…[46] The E b and SP/e calculations obtained for the QW1 structure, which we consider as a reference, are in agreement with the literature. [5,17,25,34,44,45] In line with the calculations for the QW1 structure, we have calculated the binding energies and self-polarizations for the QW2, QW3, and QW4 structures. In Figure 1, the change of E b according to the well width for four different QWs is shown in the position z i ¼ L/4 of impurity at F ¼ 0 and 50 kV cm À1 values of the electric field.…”

“…Our results are supporting the results of Figure 1 and are in agreement with. [34] In Figure 3, we have examined the change of E b versus the electric field for four different QWs for well width L ¼ 100 Å and the position z i ¼ L/4 of impurity. It has been observed that the effect of the electric field on the E b is more effective in QW4 and QW1 structures compared to QW2 and QW3.…”

“…[20][21][22][23] Under these external effects, it is possible to find many studies in which binding energy (E b ) and self-polarization (SP/e) calculations are made for the confinement electron, especially in QW1-doped semiconductors. [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43] Recently, the SP/e, which is defined as the influence of the well potential on the impurity atom has been studied for QW1 as a function of well width, external electric field, and the impurity position. In our previous studies, we have studied SP/e in QW1 under the laser field.…”

Simultaneous effects of hydrostatic pressure and applied electric field on the impurity-related self-polarization in GaAs/Ga1−xAlxAs multiple quantum wells

“…Erdogan et al found that the self-polarization of impurities in cylindrical QWW has a great dependence on the applied electric and magnetic fields [10,11], whereas in a square QWW, the self-polarization depends strongly on the axial component of the electric field [12]. It is found that the hydrostatic pressure tends to decrease the selfpolarization, but the hydrostatic pressure effects are strongly influenced by the impurity position and the applied electric field [13].…”
