        abstract = {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 ({\ensuremath{\lambda}} = 3?5 {\ensuremath{\mu}}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 {\ensuremath{\lambda}} = 3.4 {\ensuremath{\mu}}m versus 39\% at {\ensuremath{\lambda}} = 4.2 {\ensuremath{\mu}}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.}
