FIG. 1.

Differential transmission at (a) GS and (b) ES wavelengths at different reverse biased voltages. The dynamics in the (0–4 V) range consists of a two stage recovery. In the (5–9 V) range, a single stage recovery is present suggesting linear relaxation.

FIG. 2.

Experimental GS carrier relaxation for different reverse biased voltages (black) and fitting (blue) with Eqs. (1)–(3): (a) , (b) , (c) , and (d) . The other fitting parameters were and . The red (dashed) lines correspond to fitting with Auger-like ES to GS relaxation using Eq. (5).

FIG. 3.

The parameter and its fitting to as a function of voltage with and .

FIG. 4.

Experimental ES carrier relaxations (black) and fitting (red) with Eq. (5) for different voltages (0–3 V). . Other parameters are the same as in Fig. 2. The blue (solid) lines correspond to fitting with phonon-assisted relaxation using Eq. (3).
