Multifunctional controlled IR-emitting element

Results of investigations of the multifunctional emitting element based on a p + -p-p + Ge structure with anisotropic conductivity induced by magnetic field are presented. It was shown that the presence of complex controlled concentration profiles in the element essentially widens functional possibilities of the emitting element, which enables to model positive, negative or alternating contrast. This provides possibility to use it as a base in the specialized emitting sources intended for the calibration of infrared systems.
