摘要
GaN and light-emitting diodes (LEDs) with InGaN/GaN multiple quantum wells (MQWs) were grown on a-plane sapphires under different reactor pressures by metalorganic chemical vapor deposition (MOCVD). X-ray diffraction (XRD) and atomic force microscopy (AFM) measures were performed to characterize the epitaxial films. Reverse bias current-voltage (I-V) characteristics and electroluminescence (EL) intensities of LEDs were measured. GaN film grown under higher reactor pressure showed better quality, and LED on it showed improved performance. (C) 2004 Elsevier B.V. All rights reserved.
