- Gold on the move…︁ A novel growth phenomenon of axial InAs/GaAs nanowire heterostructures catalyzed by Au particles was observed. Transmission electron microscopy has determined a sequence of events: 1) Displacement of the Au particle at the end of the nanowire due to InAs clustering, 2) further InAs growth leading to sideways movement of the Au particle, and 3) eventual downward nanowire growth due to the preservation of a Au/GaAs interface (see scheme).
