GeTe nanowires are promising for enhancing the performances of the GeTe-based devices as phase change memory. GeTe nanowires have been demonstrated using Au nanoparticles as the catalyst. However, the nanowires using Ag catalyst have not been reported yet, despite the expectation for Ag-GeTe nanowire for ECM memory and the platform of thermo-electric devices. In this paper, we demonstrate GeTe nanowire growth using Ag nanoparticles as the catalyst. We find that the nanowires consist of rhombohedral GeTe crystal phase, and are grown by a catalyst-on-bottom mode.
