Abstract
High brightness InGaN/GaN multiple quantum well structures have been grown on sapphire substrates by metalorganic chemical vapor deposition, for wide range visible light emitting diode application. The compositions and sizes within quantum wells were designed according to the requirements on the LED performance. Samples were investigated by a variety of characterization techniques. Optimization of the growth parameters and process was realized and evidenced by high resolution X-ray diffraction measurements. Optical spectroscopic properties were further studied and quantum confined stokes shift was observed from room temperature and low temperature photoluminescence as well as time resolved photoluminescence measurements.
