Utilize information to define why infrared detectors

Reference no: EM13664312

Compute the thermal energy kT at room temperature in comparison with the band gap energy of a semiconductor with a band gap that corresponds to a wavelength of 1000 nm. Utilize this information to define why infrared detectors using semiconductors are usually cooled to low temperatures example 77 K using liquid nitrogen to reduce dark current that is electrical signal in the absence of an IR source.
