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.
