Growth and Characterization of GaAs/AlGaAs Core-Shell Nanowires and AlGaAs Nanotubes
We report on the fabrication of GaAs/AlGaAs core-shell nanowires (NWs) and AlGaAs nanotubes by SA-MOVPE and their photoluminescence characterization. The fabrication started from a preparation of patterned GaAs (111) B substrates partially covered with SiO2 [...]
