(a) Kinetics of the sum of the transmittance changes as determined by PP and used for the determination of the nonequilibrium carrier lifetime from the exponential part of the decay. Full circles, open circles, squares, and triangles represent data from the reference sample and the ones implanted with doses of , , and , respectively. The corresponding values for are , , , and (see from the top to the bottom). Note that for clarity, only one of five actually measured data points is displayed. (b) Nonequilibrium carrier lifetime vs implantation dose for excitation densities of 0.17 and (see full and open circles, respectively). The squares represent the data according to Ref. 11. The full line corresponds to a fit to .

Structure-specific electronic parameters vs excitation for the samples with different proton implantation doses. High density measurements [see (a)–(c), right part] are accomplished by FWM, whereas the lower density data [(c), left part] are obtained by PP. (a) Hole mobility and (b) electron mobility vs excitation density. Full circles, open circles, and squares represent data from the reference sample and the ones implanted with doses of and , respectively. (c) Spin relaxation time averaged for all samples investigated.

FIG. 3.

Spin relaxation time vs electron mobility as obtained from FWM measurements at high excitations. The straight line represents a linear fit to all data and points to . Full circles, open circles, and squares represent data from the reference sample and the ones implanted with doses of and , respectively.
