英文摘要 | High-reflectivity aln/gan distributed bragg reflectors (dbrs) were grown on c-plane sapphire substrates by metalorganic chemical vapor deposition (mocvd). a low temperature (lt) predeposition aln layer and indium doping during the growth of the lambda/4 aln layers were adopted to improve the quality of the dbr. during the growth of the dbr, the structural alternation occurred abruptly when an aln layer was grown on a gan layer but gradually in reverse order, which resulted in a stack of quasi-three-layer periodic arrangement rather than two-layer arrangement for one growth period. the peak reflectivity of dbrs reaches 99% at the designed wavelength. the root mean square (rms) roughness of the surface is around 4 nm over a 10 mu m x 10 mu m surface area of the dbr. meanwhile, the high-reflectivity (93%) and crack-free dbr with only 16-period aln/gan structures was obtained by employing an optimized aln predeposition layer. |
