英文摘要Abstract inp-inas-inp multi-shell nanowires (nws) were grown in the wurtzite (wz) or zincblende (zb) crystal phase and their photoluminescence (pl) properties were investigated at low temperature (≈6 k) for different measurement geometries. pl emissions from the nws were carefully studied in a wide energy range from 0.7 to 1.6 ev. the different features observed in the pl spectra for increasing energies are attributed to four distinct emitting domains of these nano-heterostructures: the inas island (axially grown), the thin inas capping shell (radially grown), the crystal-phase quantum disks arising from the coexistence of inp zb and wz segments in the same nw, and the inp portions of the nw. these results provide a useful frame for the rational implementation of inp-inas-inp multi-shell nws containing various quantum confined domains as polychromatic optically active components in nanodevices for quantum information and communication technologies.
