Study of InAs nanowires intersections formation by growth on an (001) oriented InAs substrate

MergedInAs nanowire intersections are grown by gold assisted VLS-MBE on (001) InAs. This is a first step toward therealization of a network of such nanowires. While InAs nanowires play already a leading role in the search for Majorana fermions, a network of such nanowires is expected to promote their exchange and allow for further development of this field. We studied the structural properties of merged InAs nanowire intersections using scanningand transmission electron microscope imaging. At the heart of the intersection, a sharp change of the crystal structure from wurtzite to perfect zinc blende is observed.
