We present a macroscopic terahertz detector based on optically thick films of dense and aligned carbon nanotubes. This p-n junction detector responds to a broad range of frequencies, shows a response at zero bias, good linearity with THz power, and is intrinsically sensitive to polarization. A combination of electrical, thermal, opto-thermal, and thermoelectric experiments establishes the photothermoelectric mechanism of the response.
