Abstract :
Growth of electroluminescent devices operating at 2 /spl mu/m based on quantum cascade (QC) design of strain-compensated In/sub x/Ga/sub 1-x/As/In/sub y/Al/sub 1-y/As has been undertaken. Experimentally measured current-voltage characteristics are in good agreement with theoretical predictions.
