| Abstract: | Fast and sensitive detection of far-infrared radiation pulses have been observed in large-area Sb thin films by means of transverse photon drag of free carriers. The direct sensitivity was greater than 1 V/MW, about 10–30 times the normal sensitivity of Ge photon drag at 10 μm wavelength. These films are ideal for power detection of fast large-area FIR pulsed emissions. |
