To explore the growth mechanism and the effect of non-gold catalysts in growing III-V epitaxial nanowires, InAs nanowires were grown on GaAs(111)B substrates using annealed Pd thin film as catalyst. Through detailed scanning and transmission electron microscopy (SEM/TEM) characterisations, it is found that when the catalyst size is less than 50 nm (from annealing the Pd thin film), defect-free zinc-blende structured epitaxial InAs nanowires are grown along the <110> directions with four 111...[Show more]
