| Abstract: | The thermal conductivity of chemically, structurally, and isotopically highly pure germanium single crystals is investigated
experimentally in the temperature range from 2 to 300 K. It is found that the thermal conductivity of germanium enriched to
99.99% 70Ge is 8 times higher at the maximum than the thermal conductivity of germanium with the natural isotopic composition.
