Abstract
The controlled growth of MgO nanorods was investigated under electron
irradiation in transmission electron microscopes at accelerating
voltages from 120 to 300 kV in the temperature range from −175 to 610
°C. The nanorod growth on the surface of MgO crystals was induced by Au,
Pt, Ni, or Co particles of 2−4 nm in size. The nanorods were grown up
to 8 nm after 5−30 min of electron irradiation time with beam current
densities of 100−600 A/cm2. The mechanism of nanorod
formation and growth is explained on the basis of electrostatic
interactions between positive ions of MgO species and negatively charged
metal particles.
