Abstract
A single quantum well Light Emitting Diode (LED) is designed from two different semiconductors and the main advantages of quantum well structure are high radiative efficiency, surface recombination etc. We have designed the device in order to observe the impact of mole fraction on power spectral density at different wave length by keeping the anode voltage fixed. A nearly lattice matched AlGaN-InGaN-GaN double hetero-structure semiconductor device has been simulated to get the maximum power spectral density at a particular wave length. For the anode voltage of 5V, at a mole fraction of x= 0.24 for Indium in InxGa1-xN, it is observed that a power spectral density of 9.31 W/cm-eV is obtained at a wave length of 452 nm. Observations were made for mole fraction varying from x=0.01 to 0.30.
