In the measurements of the spectral responses of PbTe/PbSnTe p-n heterojunction infrared detectors, the authors have discovered that there is an anomalous phenomenon in a few detectors when reverse bias is applied: there is not only a response peak in the 8-14 {mu}m long-wavelength range, but also another response peak in the 3-6 {mu}m short-wavelength range. They have also discovered that when reverse bias is increased, the heights of both spectral peaks can be adjusted, and the height of short-wavelength peak may be quickly increased, even if its long-wavelength peak is exceeded. This is an unreported new phenomenon up to now. It is shortly called anomalous phenomenon,' or Two Peak Effect' (TPE). This paper describes the new effect TPE' firstly, and makes a theoretical explanation. On the basis of this effect, it would be possible to make a new type of IR detector, which is quite different from the available detectors.
