Abstract
Spin-resolved single-electron tunneling in GaAs/AlGaAs double-barrier resonant tunneling structures is used to investigate the spin-splitting of fully quantized electronic states. With the use of magneto-tunneling spectroscopy we evaluated the Landé g-factor of GaAs quantum dots of different confinement strengths. We observe with increasing confinement a shift of the Landé-factor from the bulk GaAs-value towards positive values. Our results are compared to a multiband-k·p-calculation.
