The germanium nanowires produced by this method have superior electronic properties compared to silicon and can be used as high - capacity anode material for lithium - ion batteries, but the nanowires were previously too expensive and difficult to produce.
Scanning electron micrograph image of
germanium nanowires electrodeposited onto an indium tin oxide electrode from aqueous solution.
Now, researchers at the Missouri University of Science and Technology have shown for the first time that
germanium nanowires can be deposited by a simple, one - step process called electrodeposition that could provide a low cost route to fabricate these anodes.

germanium nanowires made by a simple, one - step process.»
In a study, reported in the January 21, 2016 issue of Nano Letters, the team demonstrated a new redox - responsive assembly method to synthesize hierarchically structured carbon - sheathed
germanium nanowires (c - GeNWs) on a large scale by the use of self - catalytic growth process assisted by thermally decomposed natural gas.
In their approach, they discovered that
germanium nanowires are grown by the reduction of germanium oxide particles and subsequent self - catalytic growth during the thermal decomposition of natural gas, and simultaneously, carbon sheath layers are uniformly coated on the nanowire surface.
