Synthesis of Silicon Nanotubes in Arc Argon Plasma at Moderate Currents

This work describes the process of synthesis of silicon nanotubes and nanowires in an argon arc. Evaporation of silicon atoms is carried out from crystalline silicon placed in the well of a graphite anode. The electrodes were placed in a plasma reactor in an upright position at an argon pressure of 450 Torr. During the discharge, silicon atoms evaporated from the anode surface. Deposits formed on the surface of the graphite cathode, which were silicon nanotubes and nanowires. The synthesized samples were analyzed on an electron microscope.
