Phonon Reflections From Solid-Solid Interfaces
The first two chapters of this book separate the Kapitza boundary resistance problem into two parts: classical solid-solid interfaces, which obey classical theory, and solid-liquid helium interfaces which behave in an anomalous way yet to be understood. In this note we present evidence which tends to a surprising conclusion: that the anomalous behavior is a very widespread—perhaps even universal— property of imperfect interfaces between any two media. If this view is correct, then the subjects covered in Ch. 1 and Ch. 2 differ only in the relative importance of the normal and the anomalous channels for transmitting heat at an interface.
