A new very fast noise-immune uncooled photodetector was developed on the basis of the intraband photoconductivity. The detector was found to have a time resolution of 2 × 10 10 sec and an output voltage up to 8 V. The dependence of the relative photoconductivity Δ σ /σ on the carrier density was determined at room temperature at various wavelengths. The responsivity of the photodetector was determined as a function of the wavelength, voltage, and illumination intensity.
