Abstract :
Unusual enhancement of mid-infrared light emission from CdTe/PbTe heterostructures is observed. It is discovered that the observed intense mid-infrared luminescence in the structures comes from the inherent polar interface character and coupling of surface plasmons localized at the metallic CdTe/PbTe interface to light emitted from the narrow gap PbTe.
