Image of FIG. 1.
FIG. 1.

PL spectra of the two ultrathin InAs samples. The inset is the excitation-power dependence of the PL intensity in log scale.

Image of FIG. 2.
FIG. 2.

PL decay curves of two ultrathin InAs samples at : (a) 1 ML InAs and (b) ML InAs. Note that the left ordinate is in a natural logarithm scale. The insets show the PL decay time as a function of temperature.

Image of FIG. 3.
FIG. 3.

Typical time-resolved spectra of the and luminescence components of the 1 ML (a) and ML (b) InAs samples at , under excitation density of . The spectra are taken after excitation.

Image of FIG. 4.
FIG. 4.

Spin splitting energy as a function of delay time, along with time evolution of the polarizations for the 1 and ML InAs samples, respectively. The inset shows the splitting energy as a function of the excitation density, measured at time delay of .
