LED-like structures with high temperature superlinear luminescence
Original language description
The superlinear electroluminescence (SLEL) of the structures based on AlSb/InAsSb/AlSb deep quantum wells (QWs) grown by MOVPE on n-GaSb:Te substrates is presented. Two different Sb compositions were grown. Dependence of the electroluminescence spectra and optical power on the drive current in nano-heterostructures at 77-300 K temperature range was measured. Intensive two-band SLEL in the 0.5-0.8 eV photon energy range and optical power enhancement with the drive current at room emperature caused by the contribution of the additional electron-hole pairs, generated at AlSb/InAs interface, due to the impact ionization by the electrons heated at the high energy difference between AlSb and the first electron level Ee1 in the InAsSb QW were found.n
