A Sonochemical Approach to the Synthesis of Crystalline Selenium Nanowires in Solutions and on Solid Supports

Single crystalline selenium nanowires have been successfully synthesized using a sonochemical process. These uniform nanowires can be grown in solutions or on substrates at room temperature with yields approaching 100 %. The nanowires could also be directed to grow into self-connecting networks (see Figure), and to form electrically continuous connections between two electrodes.
