We have investigated the catalyst-free selective-area growth of GaAs and GaAs/InxGa1-xAs/GaAs (0x3. GaAs nanowire length would become longer by reducing the mask opening size. Thus we can form the GaAs nanowire uniform arrays with appropriate length and width by controling growth conditions and mask opening size. Then the photoluminescence measurement of GaAs/InxGa1-xAs/GaAs (0x<1) core-shell nanowires is carried out.
