中文摘要 | we report the structural and optical properties of nonpolar m-plane gan and gan-based leds grown by mocvd on a gamma-lialo2 (100) substrate. the tmga, tmin and nh3 are used as sources of ga, in and n, respectively. the structural and surface properties of the epilayers are characterized by x-ray diffraction, polarized raman scattering and atomic force microscopy (afm). the films have a very smooth surface with rms roughness as low as 2nm for an area of 10 x 10 mu m(2) by afm scan area. the xrd spectra show that the materials grown on gamma-lialo2 (100) have < 1 - 100 > m-plane orientation. the el spectra of the m-plane ingan/gan multiple quantum wells leds are shown. this demonstrates that our nonpolar led structure grown on the gamma-lialo2 substrate is indeed free of internal electric field. the current voltage characteristics of these leds show the rectifying behaviour with a turn on voltage of 1-3 v. |
