摘要：

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% Ge-70 is 8 times higher at the maximum than the thermal conductivity of germanium with the natural isotopic composition.
