Abstract

By means of chemical vapor transport using iodine and bromine as transport agents in the system Cu/Ge the compounds Cu3Ge (ε and ε1), Cu3Ge (ζ) and copper-rich mixed crystals Cu(Ge) have been prepared in form of single crystals. Thermodynamic considerations allow to understand the CVT process, especially the unexpected low temperatures. Copper suicides can be prepared under similiar conditions. They are extremely disordered. Their crystallographic characterisation was therefore impossible.
