a-d, OPTP transients of the control (a), MA (b), PEA (c) and t-BA (d) films measured after an excitation with a 410 nm pump pulse (50 fs duration) at various fluences. Solid lines are the rate equation fits to the fluence-dependent transients (Supplementary Note 6). Error bars represent the standard error obtained from eight independent measurements (n = 8). e-h, Derived effective THz mobilities φ∑μ of the control (e), MA (f), PEA (g) and t-BA (h) films at early times (0–10 ps). Error bars represent the standard error obtained from eight independent measurements (n = 8).
