Paper Abstract

The homoepitaxial growth InGaN/GaN double heterostructure (DH) light emitting diode (LED) by low pressure metalorganic chemical vapor deposition is reported for the first time. Hydride Vapor Phase Epitaxy prepared 350micrometers -thick GaN single crystal was polished down to a surface roughness of 10 angstrom rms to serve as the substrate. The LED exhibited luminous intensity of 850mcd and forward voltage of 5V at a current of 20mA. The peak wavelength and full width at half maximum of electroluminescence were 490nm and 83nm, respectively.
