Semiconductor nanowires offer the possibility of enhancing the degree of freedom for 3D integration. Metallic nanoparticles have shown promising applications in plasmonic, nanowire synthesis, etc. The combination of semiconductor nanowires with metallic nanoparticles in self-assemble way may open up new opportunities for novel applications in optoelectronics and nanostructure synthesis. Here we report self-assembled hybrid nanowire-nanoparticle 3D system with aligned indium and bismuth nanoparticle on nanowire side faces. This is enabled by using nanowires with the tapering shape. Indium and bismuth nanoparticles can be preferentially aligned into an 1D array on the side (112) face. This work opens up new opportunities for development of novel applications by combing metallic nanoparticle and semiconductor nanostructures.
