Luminescence Mechanism in Green InGaN/GaN LED with An Insertion Layer Between The Multiple Quantum Wells and n-GaN Layer[J].

The green light emitting diode (LED) with an insertion layer between the multiple quantum wells and n-GaN layer was grown on
c
-plane sapphire substrate by metal organic chemical vapor deposition. The structural and optical properties of the LEDs with and without insertion layer were investigated. It is found that the insertion layer can promote the combination of In concentration
and induce an overall red-shift of wavelength. We speculate that the In phase separation and piezoelectric field would be responsible for the wavelength red-shift
the performance of LED deteriorated either.
