Explain the Einstein model for the heat capacity of a lattice. How do its predictions compare?
Explain the Debye model for the heat capacity of a lattice. In which respect does it work better than the Einstein model and why?
Einstein model of specific heat works at high-temperature, however, it doesn't work at lo temperature. Debye model works better than the Einstein model. The full derivation is uploaded here from image 1 to 5.
