Rod with a length of 0.5-4 m and a diameter of 25-220 mm made of a high-purity alloy deposited on silicon thin rod or germanium alloyed silicon thin rod, where the alloy comprises 0.1-50 mol.% of germanium and 99.9-50 mol.% of silicon, and has a polycrystalline structure, is claimed. An independent claim is included for preparing the rod comprising feeding educt gases in a Siemens reactor and contacting with a glowing thin rod, where a deposition of the educt gas is formed on the thin rod, the thin rod comprises silicon or germanium alloyed silicon and the educt gas comprises hydrogen, at least a silicon-containing compound and at least a germanium containing compound. |
