“…1 (a), corresponding to the positively charged exciton (X + , 908.1 nm), exciton (X, 911.3 nm) and biexciton emission (XX, 912.5 nm). These emission lines have been identified previously using the polarization-resolved PL spectra [21,22]. In addition, a broadened emission peak is observed at a wavelength of 872.2 nm and is assigned to the two-dimensional exciton emission in the WL.…”

“…Currently, a promising system for these tasks are donor-bound electrons in ultrahigh quality, very weakly n-doped GaAs since the widely spaced, quasi-isolated electrons act as an ensemble of identical, individually localized atoms [5,6]. However, the ostensible catch of this approach is the inherent interaction with the nuclear spin bath which has been addressed in many different systems so far [7][8][9][10][11].In principle, there are different approaches to deal with the decoherence imposed via the hyperfine interaction. On the first sight, the most obvious way is to replace the isotopes carrying a nuclear spin with spinless isotopes like in 28 Si [12] but silicon has the drawback of an indirect gap.…”
