15 November 2002 Chalcogen nanowires: synthesis and properties
Author Affiliations +
We have demonstrated a solution-phase approach based on homogeneous nucleation and controlled growth for the synthesis of 1-dimensional nanostructures from a chalcogens such as Se, Te, and Se/Te alloys. These nanostructures include monodispersed nanowires, nanorods, and nanotubes with good dimensional control (lateral dimensions from 10 to 1000 nm, and lengths ranging from a 0.25 to >20 μm). These nanomaterials are ideal components for fabricating devices or composites for photoconductive and piezoelectric applications. In this presentation, we will discuss the mechanisms (as revealed by our SEM and TEM studies) for the formation of these 1-dimensional nanostructures, as well as some preliminary measurements on their properties.
