abstract = {We demonstrate the growth and structural characteristics of
InAs nanowire junctions evidencing a transformation of the
crystalline structure. The junctions are obtained without
the use of catalyst particles. Morphological investigations
of the junctions reveal three structures having an L-, T-,
and X-shape. The formation mechanisms of these structures
have been identified. The NW junctions reveal large sections
of zinc blende crystal structure free of extended defects,
despite the high stacking fault density obtained in
individual InAs nanowires. This segment of zinc blende
crystal structure in the junction is associated with a
crystal phase transformation involving sets of Shockley
partial dislocations; the transformation takes place solely
in the crystal phase. A model is developed to demonstrate
that only the zinc blende phase with the same orientation as
the substrate can result in monocrystalline junctions. The
suitability of the junctions to be used in nanoelectronic
devices is confirmed by room-temperature electrical
experiments.},
