Superlinearity and temperature dependence of electroluminescence in heterostructures with deep AlSb/InAs1-xSbx/AlSb quantum well

Original language description

We report on superlinear electroluminescent structures based on AlSb/InAs1-xSbx/AlSb deep QW grown by MOVPE on n-GaSb:Te substrate. Intensive two-band superlinear EL in the 0.5-0.8 eV photon energy range was observed. Optical power enhancement with the increasing drive current at room temperature is caused by the contribution of the additional electron-hole pairs due to the impact ionization by the electrons heated at the high band offset between AlSb and the first electron level Ee1 in the InAsSb QW. Study of the EL temperature dependence enabled us to define the role of the first and second heavy hole levels in the radiative recombination process. It was shown that with the temperature decrease, the relation between the energies of the valence band offset and the second heavy hole energy level changes due to the temperature transformation of the energy band diagram.
