In this Letter, the authors demonstrate for the first time the epitaxial growth of alternating InP-InAs nanowire heterostructures using Cu seed particles. The use of seed particle materials alternative to gold, which is the most common material for III/V nanowires, may lead to new and unexpected growth features. In the case of this investigation, 3D nucleation and extended segments of the 4H polytype are observed.
