Abstract

The violet-LEDs structure with InGaN/GaN multi-quantumn-wells (MQW) was grown by low-pressure metalorganic chemical vapor deposition (LP-MOCVD). The x-ray diffraction (XRD) revealed distinct second order satellite peak. The photoluminescence (PL) wavelength was about 399.5nm with FWHM of about 15.5nm. InGaN/GaN MQW violet-LEDs have been successfully fabricated with EL wavelength of 402nm and forward voltage about 3.6V under 20 mA injection current.
