Abstract: Low temperature electroluminescense is performed on InAs/InSb/GaSb structures under varying magnetic field. The samples studied consist of a single narrow InAs quantum well (QW) grown below a layer of InSb quantum dots (QDs) separated by an undoped GaSb spacer layer whose thickness is varied. Electroluminescence in the region of 1.7-2.6 µm is observed in this system and is believed to be associated with electronic coupling of wavefunctions through the intervening spacer layer between the dots and the well. Magnetoelectroluminescence measurements are performed at 2 K in a 21-Tesla VTI cryostat with pumping currents of 5-100 mA and continuous magnetic field perpendicular to the sample plane. The experimental results show apparent shifts of the emission energy with a dependence on magnetic field, providing evidence that the emission energy can be ascribed to strainmediated correlation of the localised states in the system
