Obtaining of silicon nanowires becomes eco-friendly
Scientists from the Faculty of Physics, the Lomonosov Moscow State University have worked out a new and more eco-friendly method of silicon nanowires obtaining, which allows to replace hydrofluoric acid (HF) by ammonium fluoride (NH4F). Silicon nanowires are streamlined, almost parallel to each other nanostructures, looking like wires. Nanowires diameter varies from 50 to 200 […]
