In this paper, we have proposed a “Chess board” like photonic crystal (PhC) structure on top surface of p-GaN/SiO2 layer in conventional LED, on top surface of n-GaN layer in vertical LED and an embedded PhC structure in n-GaN layer for achieving an improved light extraction in GaN/InGaN LEDs. The results are compared with that of the LED structures with conventional 2-D PhC structures and of the conventional LEDs. Results from these simulations show that the maximum light extraction for… CONTINUE READING
