英文摘要	The authors report the self-organized growth of inas/inalas quantum wires on nominal (001) inp substrate and (001) inp substrates misoriented by 2 degrees, 4 degrees, and 8 degrees towards both [-110] and [110]. the influence of substrate misorientation on the structural and optical properties of these inas/inalas quantum wires is studied by transmission electron microscopy and photoluminescence measurements. compared with that grown on nominal (001) inp substrate, the density of inas/inalas quantum wires grown on misoriented inp(001) substrates is enhanced. a strong lateral composition modulation effect take place in the inalas buffer layers grown on misoriented inp substrates with large off-cut angles (4 degrees and 8 degrees), which induces a nucleation template for the first-period inas quantum wires and greatly improve the size distribution of inas quantum wires. inas/inalas quantum wires grown on inp (001) substrate 8 degrees off cut towards [-110] show the best size homogeneity and photoluminescence intensity.
