Figure 10. Differential transmission transients from series A films when probing the 1Sh-1Se (a), 1Ph-1Pe (b) and sub-gap states ~150 meV below 1Sh-1Se (c) at 300 K.
Differential transmission signals at pump-probe delay times of 0 (d) and 100 ps (e) for all measured probe energies. Absolute differential transmission at t = 0 versus pump energy along with allometric curve fits.
