Abstract
We use magneto-tunneling spectroscopy to investigate the Landé g factor of single self-assembled InAs quantum dots. With increasing ground state energy we find an increase of g. For different orientations of the magnetic field with respect to the crystallographic axes we mapped the anisotropy of the effective electron g factor. In addition to the strong anisotropy for tilting the field from the growth direction [1 0 0] into the direction [0 1̄ 1̄] a smaller, but measurable anisotropy is detected for changing the magnetic field direction from [0 1̄ 1̄] to [0 1̄ 1].
