Oriented growth of magnesium nanowires by physical vapor deposition in high vacuum

[Display omitted] [11−20]-oriented magnesium nanowires were prepared at 703K for 30min in a high vacuum level of 10−4Pa by physical vapor deposition method. The evaporation temperature and vacuum level are the two key factors in the preparation of the magnesium nanowires. A growth mechanism that the magnesium nanowires prefer to grow in the closest packed direction, which has the largest binding strength, is proposed to explain the oriented growth of the magnesium nanowires.
