We report on the THz emission from a well-aligned, chirality-enriched (6,5) semiconducting CNT thin film on a sapphire substrate with a dipole-type photoconductive antenna fabricated on top of the film. The device was photoexcited with femtosecond pulses corresponding to the E22 absorption peak for (6,5) single-wall CNT. The very high-degree of CNT alignment in the film resulted to a large excitation polarization-dependence of the THz emission. Using CNT as base material allows the application of relatively high voltage across the device which could be an advantage in designing strong THz emitters. Our work here demonstrates the possibility of incorporating CNT in various THz devices. |
