A major advantage of semiconductor nanowires (NWs) is the possibility to integrate these nano-materials on various substrates. This perspective is particularly attractive for III-nitrides, for which there is a lack of an ideal substrate. We examined the use of novel templates for growing GaN NWs by plasma assisted molecular beam epitaxy. We explored three approaches with a common feature: the base support is a cost-efficient amorphous substrate and a thin crystalline material is deposited on the support to promote epitaxial growth of GaN NWs.In the first approach, we formed polycrystalline Si thin films on amorphous support by a process called aluminum-induced crystallization (AIC-Si). The conditions of this process were optimized to get a ...
