Spectra and quantum efficiency h e of green LEDs based on heterostructures InGaN/AlGaN/GaN with multiple quantum wells were studied at currents J = 10 ยฑ ยฑ6 to 10 ยฑ ยฑ1 A. Minor differences in h e (of AE10% at J % 10 mA) are caused by sufficiently different distributions of effective charges in the sp
