Abstract

The performance of near-room temperature long-wavelength photovoltaic IR detectors has been analyzed. The ultimate performance of the devices is limited by the noise due to the statistical nature of thermal generation and recombination processes. Another practical limitation arises from the Johnson-Nyquist noise due to parasitic impedances and contribution of preamplifier noise. This is particularly significant for large area devices. Possible ways to overcome the difficulties are discussed.
