This presentation describes an electrochemical liquid-liquid-solid (ec-LLS) process that produces large amounts of crystalline semiconductors with tunable nanostructured shapes without any physical or chemical templating agent. We will describe our initial and latest efforts using this process to produce nanostructured polycrystalline group IV and III-V semiconductors under ambient conditions. Electrodeposition involving a liquid electrolyte, a liquid electrode, and a solid deposit under ambient conditions represents a conceptually unexplored direct wet-chemical route for the preparation of bulk quantities of crystalline optoelectronic materials. Control of the saturation and precipitation of through the applied bias affords a variety of material morphologies, including dense ?lms of oriented nanostructured ?laments with large aspect ratios. The presented strategy offers the possibility of material synthesis without the time- and energy-intensive processing steps required in traditional thermochemical syntheses of semiconductor materials. Data will be presented illustrating the utility of the as-prepared materials.
