Abstract
Room‐temperature electroluminescence at peak wavelengths of 5–7 μm has been observed in metalorganic vapor phase epitaxy‐grown mercury cadmium telluride, fully impurity doped, heterostructure, mesa diodes. The internal quantum efficiency at low injection for 5 μm emission is around 4×10−4. Maximum output power at 295 K is 6 nW from an 80 μm diameter device (120 μW cm−2) at 50% duty cycle. The dependence of intensity on current, the emission spectra, and an infrared microscope image of the emission are presented.
