We report the epitaxial growth of defect-free zinc-blende structured InAs nanowires on GaAs{111}B substrates using palladium catalysts in a metal-organic chemical vapor deposition reactor. Through detailed morphological, structural, and chemical characterizations using electron microscopy, it is found that these defect-free InAs nanowires grew along the 〈1̄1̄ 0〉 directions with four low-energy {111} faceted side walls and {1̄1̄3̄} nanowire/catalyst interfaces. It is anticipated that these...[Show more]
