Controlled Synthesis of Se/Te Alloy and Te Nanowires

"Se/Te alloy and Te nanowires (NWs) with different morphologies were synthesized through a novel, control-lable solution-phase method. Sodium dodecylbenzene sulfonate was employed as a surfactant to control the reaction rate in the synthesis. Through reaction process dynamics control, both "bending" and "V-shaped" Se/Te alloy NWs were controllably produced. The phase structures and morphologies of the Se/Te and Te products were investigated with XRD, TEM, and HRTEM. The formation mechanisms of the NWs were investigated on the basis of the experimental results. The significance of these results lies in the important implications concerning the potential use of these NWs materials for nanoscale electronic devices."
