Abstract
Energy levels and oscillator strengths for transitions between the lowest states of an acceptor in a semiconductor quantum dot with a finite potential barrier have been computed in the effective-mass approximation, with the valence-band degeneracy in cubic semiconductors taken into account in the spherical approximation. Variational envelope functions have to satisfy the appropriate boundary conditions to ensure the hermiticity of the Hamiltonian matrix. In typical cubic semiconductors the acceptor optical transition energies and oscillator strengths are found to have enhanced values, larger by one order of magnitude than those in the bulk, in the dots of radius approximating in value to the diameter of the acceptor ground-state envelope.
