The presented results show that the spectrum of thermal radiation from a semiconductor plate whose opposite faces are parallel to each other demonstrates an oscillating character. This is due to the interference effects in the Fabry-Perot resonator. The spectrum features strongly depend not only on the plate thickness, but also on such parameters as plasma frequency () and damping coefficient (). The electron-hole plasma frequency can be easily varied by photo-excitation, injection of electrons or holes, and other techniques. So one can hope that the study of thermal radiation from such semiconductor elements would allow developing new efficient and controlled IR radiation sources.
