Abstract
Electroluminescence is reported for the first time from InAs0.75Sb0.25 quantum dot light emitting diodes. The quantum dots were grown from the liquid phase at 590 degree(s)C on an InAs (100) substrate and embedded within the undoped active region of an InAs homojunction pin diode. At 4K and 250 mA injection current, three transitions were identified, centered at 4.01, 3.80 and 3.63micrometers , associated with the sp, p and d states of the confined holes inside the quantum dot. Each of the transitions exhibits a blue shift with increasing injection current, but the electroluminescence results indicate the presence of a phonon bottleneck in these devices. The quantum dot electroluminescence was observed to persist up to room temperature.
