Figures

FIG. 1.

(Color online) (a) Pump-probe scans of QD ellipticity signal at different magnetic fields (Bx ) applied in Voigt geometry. (b) Decomposition of electron and hole signals at B = 1 T. (c) Electron and hole spin precession frequency vs. magnetic field. Lines are linear fits to the data (see Ref. 13).

FIG. 2.

(Color online) (a) Ellipticity vs delay between pump and probe for different angles φ relative to x in the xy plane. (b) Corresponding scans at different angles ψ in the xz plane. B = 1 T, T = 10 K.

FIG. 3.

(Color online) Contour plot of electron and hole g-factor tensors from ellipticity measurements.

Image of FIG. 4.
FIG. 4.

(Color online) Angular dependence of electron and hole g-factors in (a) (x-y), (b) (x-z), and (c) (y-z) planes. The solid lines are fits to data using Eq. (1).
