The effects of temperature and hydrostatic pressure on the photoionization cross-section and binding energy of impurities in quantum-well wires

Effects of external fields, the hydrostatic pressure and temperature on the electronic Raman scattering of a hydrogenic impurity in a two-dimensional parabolic quantum dot

“…Moreover, we can write the pressure and temperature dependent dielectric constant and electron effective mass as follows [83,84]. …”

The Binding Energy of Impurities in the Asymmetrical Semi-Exponential Quantum Wells

“…It is important to understand the electronic and optical properties of impurities in these systems, because the optical and transport properties of the devices made of this material are strongly influenced by the presence of shallow impurities. Several studies have been done on the hydrogenic impurity in low-dimensional structures [13][14][15][16][17][18][19][20]. Sari et al have investigated the binding energy of shallow-donor impurities in quantum-well wires (QWWs) and quantum dots (QDs) [13][14][15][16].…”

Sari et al have investigated the binding energy of shallow-donor impurities in quantum-well wires (QWWs) and quantum dots (QDs) [13][14][15][16]. The problem of hydrogenic-like donor impurity, located at the center of a spherical semiconductor QD was investigated by Al-Hayek et al [17].…”

Spectral Parameters of Electron in a Multishell Semiconductor Cylindrical Nanotube with a Donor Impurity at Its Axis

“…The research of the binding energy of an electron with an impurity in cylindrical quantum wires or simple nanotubes faces the considerable mathematical difficulties associated with the fact that the spherical symmetry of the Coulomb interaction potential between the electron and the impurity and the nonspherical symmetry of the system have to be put in agreement with each other. Therefore, while studying the impurity-renormalized electron spectrum, the authors use the Ritz variational method in the overwhelming majority of works [10][11][12][13][14][15][16]. However, this method allows only the ground state of an electron to be described rather exactly and simply.…”
