TY - JOUR ID - zu28349 UR - http://link.springer.com/journal/11455 IS - 5 A1 - Kudryk, Y. Y. A1 - Zinovchuk, A. V. N2 - The effect of current crowding on the internal quantum efficiency (IQE) of InAsSb/InAs light- emitting diodes (LEDs) operating in the middle?infrared (mid?IR) range (? = 3?5 ?m) has been studied. Calculations based on a modified model of recombination coefficients show that current crowding leads to a significant decrease in the IQE of LEDs, which is especially pronounced in longer?wavelength devices (23% at ? = 3.4 ?m versus 39% at ? = 4.2 ?m). The obtained results indicate that the effect of current crowding should be taken into consideration as an additional nonthermal mechanism of IQE decrease in mid-IR LEDs.
