Mohamed Rabieigh brightness InGaN LEDs on c-plane sapphire substrates [., .]. Already at the end of the last century blue and green LEDs with tens and hundreds of milli-Watt output power levels were demonstrated. Today, blue InGaN LEDs boast record external quantum efficiencies exceeding 80% and the emission wav

Mohamed Rabie been greatly improved. For example, the internal quantum efficiency of the 625 nm AlGaInP-based LED can reach almost 100%. However, defects caused by the lattice and thermal mismatch, stress and electric field which present in GaN-based materials make the internal quantum efficiency of Group III ni
