  • Abstract
    We experimentally investigated the terahertz (THz) photoresponse of vertically-aligned single-walled carbon nanotube (SWCNT) films by using optical pumping method. The SWCNT film was grown on the fused quartz substrate by using the alcohol catalytic CVD process. We observed that the strong THz radiation is emitted from the photoexcited SWCNT film. Our finding is the first demonstration of THz pulse emission for the unbiased SWCNT-based films.
