Abstract
We have determined the Landé factor g* in self-organized InAs quantum dots using resonant-tunnelling experiments. With the magnetic field applied parallel to the growth direction z we find g∥* = 0.74 for the specific dot investigated. When the magnetic field is tilted away by θ from the growth axis, g* gradually increases up to a value g⊥* = 0.92 when B ⊥ z. Its angular dependence is found to follow the phenomenological behaviour g*(θ) = √(g∥* cos θ)2 + (g⊥* sin θ)2.
