Abstract

Plasma reflectivity edge in infrared reflectivity spectra measured on narrow-gap semiconductors has been found to be most sensitive to the variation of carrier concentration based upon which a new way of infrared modulation has been studied. The modulation gain in power is impressively high. Thus a less sensitive room-temperature infrared detector could be as sensitive as the existing cooled infrared detectors in detecting middle-infrared radiation. The detectivity has been calculated.
