Figure 6

Schematic illustration of a plausible mechanism for the formation of V-shape Se/Te NW and straight Se/Te NW with SDBS as surfactant,a formation of a-Se nanoparticles when adding selenious acid into the solution containing short Te nanorods and nanoparticles,b a-Se and a-Te compete together and deposited at the end of Te nanorods crystalline seeds,c V-shape structure formation and continue to grow from the seeds accompanied by the dissolution of a-Se and a-Te colloidal particles as relax energy of Te nanorods at the end sides,d formation of a-Se nanoparticles when adding selenious acid into the solution containing long Te nanorods and few Te nanoparticles,e a small amount of a-Se and large quantity of a-Te compete together and deposited at the end of Te nanorods crystalline seeds, andf Se/Te NWs with straight morphology formation and continue to grow from the seeds accompanied by the dissolution of a-Te colloidal particles
