Abstract
Free-standing Ge nanoparticles about 3 nm in size were formed using a facile colloidal synthesis method. The effect of systematic annealing in H2/Ar (%5/%95) gas medium on morphology and structure of the free-standing Ge nanoparticles was investigated using transmission electron microscopy and selective area electron diffraction techniques. We showed that upon annealing in H2/Ar (%5/%95) gas medium, the size of Ge nanoparticles can be controlled and some exotic phases such as β-Sn II phase and 4H-Ge phase seem to be formed. To our knowledge, free-standing Ge nanoparticles in 4H-Ge phase was demonstrated for the first time.
