Dedicated to Professor Jozef T. Devreese on the occasion of his 65th birthday PACS 73.21.La A theoretical description is presented for a single-electron transport through a vertical gated quantum dot. Using the configuration interaction method we study the correlation effects in the gated quantum dots. We have found that the electron-electron correlation only slightly changes the single-electron tunnelling conditions in the absence of an external magnetic field, but has a pronounced influence on the magnetic-field induced phase transitions in few-electron systems confined in quantum dots.

“…In order to separate out the static lattice deformation induced by the positive donor center and to introduce a proper screening of the electron-donor Coulomb interaction [18,24,30], we apply to the Hamiltonian of Eq. (1) the Platzman transformation [31] by means of the unitary operator…”

The effects of low electric field and finite-barrier height on the ground state energy of a donor impurity confined in a polar CdSe spherical quantum dot embedded in a non-polar matrix were studied. Calculations were carried out in the framework of the effective mass approximation using the Hassé variational approach. The effect of the quantum confinement was described by a finite deep potential taking into account the interactions between the charge carriers (electron and ion) and the confined longitudinal optical phonons (LO-phonons). It was found that the binding energy and the polarizability depend strongly on LO-phonon effects. So, the phonon corrections should not be ignored or neglected whatever the dot size and the degree of confinement.
