摘要：

We have investigated the Zeeman splitting in strained InxGa1-xAs quantum dots with different quantization energies by means of magnetoluminescence. A multifold splitting of Pi and Delta states is-observed due to lifted degeneracy of m>O states. The experimental data were systematically compared to the diamagnetic and Zeeman shift of the single-particle states, taking into account the details of the valence-band structure and the spin splitting. Our data indicate that excitonic effects are negligible and that the magneto-optical properties of these strongly confined dots can be described rather accurately within the single-particle model.
