Figure 1

Photoluminescence spectra of single quantum dots in a quantum well oriented at an angle of 69° from the Faraday configuration. The spectra are offset to show their development as the applied magnetic field is increased from $0\mathrm{T}$ (bottom spectrum) to $9\mathrm{T}$ (top spectrum) in steps of $0.5\mathrm{T}$. Spectra correspond to (a) two charged excitons and (b) a neutral exciton.Reuse & Permissions

Figure 2

Photoluminescence spectra showing the spin fine structure of (a) the charged exciton and (b) the neutral exciton at $9\mathrm{T}$ as the angle is increased from 80° to 100° from the Faraday geometry (shown as deviation from a reference axis near the Voigt configuration) in steps of 2°.Reuse & Permissions

Figure 3

(Color online) Transition energies at $9\mathrm{T}$ applied field are plotted for (a) charged and (b) neutral exciton transitions as a function of absolute deviation from the angle of minimum spin splitting. Triangles and circles represent points from opposite rotations from zero. The lines represent fits to the spin Hamiltonian, with a small diamagnetic correction varying with the sine of the deviation angle. The estimated error in both transition energy and relative angle is approximately the size of the symbols.Reuse & Permissions
