Transient reflection spectrum as a function of carrier density (n) and probe photon energy E (ħω2) at pump–probe delays of Δt = 4 ps (a), 39 ps (b), 399 ps (c) and 1,399 ps (d) at 7 K, Δt = 4 ps (e), 39 ps (f), 399 ps (g) and 1,399 ps (h) at 20 K and Δt = 4 ps (i), 39 ps (j), 399 ps (k) and 1,399 ps (l) at 50 K. All measurements were conducted at a pump fluence of 54 μJ cm−2 with the transient reflection range ΔR/R0 from −2 × 10−4 to 2 × 10−4. There is no external magnetic field (B = 0) or displacement field (D = 0).
