Optimal width of quantum well for reversed polarization blue InGaN light-emitting diodes

Optimal width of quantum well for reversed polarization blue InGaN light-emitting diodes

The optical properties of reversed polarization (RP) blue InGaN light-emitting diodes (LEDs) under different quantum wells (QWs) width are numerically studied. We compared the band diagram, electron and hole concentration, emission wavelength, radiation recombination, internal quantum efficiency (IQ...
