Thermal Conductivity in the 21st Century
摘要
The study of the nature of heat continues to be an active area of research in the twenty-first century. Both improvements in theory and dramatic improvements in the laboratory have been reported. The many forms of “imperfections” in solids have been explored. Thermoelectric devices are now an important part of industrial practice. But, the fundamental truth about heat remains the same: Heat flowsHeat flow from a hot body to a cold body!
