Potential for Novel Magnetic Structures by Nanowire Growth Mechanisms
Journal of Magnetics, Volume 10, Number 3, 30 Sep 2005, Pages 108-112
Abstract
GaAs nanowires were grown on GaAs (111)B substrates in a gas source molecular beam epitaxy system, using self-assembled Au particles with diameters between 25 and 200 nm as the catalytic agents. The growth rate and structure of the nanowires were investigated for substrate temperatures between 500 and 600℃ to study the mass transport mechanisms that drive the growth of these crystals. The possibilities for fabrication of novel magnetic nanostructures by suitable choice of growth conditions are discussed.
