Abstract The two types of single-crystalline α-Ge nanowires (NWs) were synthesized at 550°C by annealing the crystalline Ge sample in the hydrazine vapor containing 3 mol.% of water. The mass transfer was accomplished by volatile GeO molecules. The tapered NWs were grown by the vapor-liquid-solid method with ∼8nm Ge catalyst droplet surrounded by ∼5nm thick GeO shell. NWs with uniform diameters were formed on the same sample by the oxide-assisted growth method. In the photoluminescence spectra of NWs the five peaks were observed in the blue-green region with energies close to the photoluminescence peaks of germanium suboxides.
