FIG. 1.

Differential transmission of the terahertz pulse as a function of pump-probe delay time obtained in Pc, FPc, and Rub crystals (all at room temperature) and in Tc (at ) upon photoexcitation with , pump pulses. The transients are offset along the y-axis for clarity. The inset shows the differential transmission of the terahertz pulse normalized to its value at and illustrates subpicosecond charge photogeneration in all samples.

FIG. 2.

Temperature dependence of the product of mobility and photogeneration efficiency calculated from the peak value of in Pc, FPc, Tc, and Rub samples. The minimum detectable product is .

Image of FIG. 3.
FIG. 3.

Differential transmission of the terahertz pulse normalized to its value at in the case of (a) FPc, Pc, and Rub samples at and (b) FPc, Pc, Rub, and Tc samples at . Insets show the FPc and Pc data replotted on a log-log scale and fitted with the power-law function (thick solid lines) with (a) and 0.6 for FPc and Pc, respectively, at and (b) and 1.1 for FPc and Pc, respectively, at . (c) Power-law exponents obtained from fits to the decay dynamics at various temperatures in one FPc and two Pc (Pc 1 and 2) single crystal samples. Dashed lines are guides for the eye.
