Abstract
The problem of detection of few-electron states has been studied for spherical quantum dots both with and without a donor centre. The confinement potential is assumed to be a three-dimensional spherical potential well of finite depth and range. The variational method has been applied to calculate bound states of one-, two-, and three-electron systems confined in donor-doped and undoped quantum dots. We have shown that the chemical potentials of the systems considered are significantly different, in contrast to the intraband optical dipole transition energies, which are almost indistinguishable. Therefore, the transport and capacitance spectroscopy techniques should yield clear evidence for the presence of a donor impurity in the quantum dot.
