SiN interlayer to improve external quantum efficiency and reduce sidewall recombination for blue (micro) light-emitting diodes
We demonstrate that inserting a fractional monolayer of SiN below the first InGaN quantum well (QW) does not change the In content but increases the external quantum efficiency (EQE) of light-emitting...
