It has been found that the radial growth of InAs was preferentially initiated on the {112}A sidewalls of GaAsnanowires. This preferential deposition leads to extraordinarily asymmetric InAs/GaAs radial nanowireheterostructures. Such formation of radial nanowireheterostructures provides an opportunity to engineer hierarchical nanostructures, which further widens the potential applications of semiconductor nanostructures.3 pageshttp://www.sherpa.ac.uk/romeo/issn/0003-6951..."Publishers version/PDF may be used on author's personal website, institutional website or institutional repository" from SHERPA/RoMEO site (as at 21/10/15).
