Debye model

The Debye model is a theory used to describe how materials respond to temperature changes, especially in solids. It helps explain how atoms vibrate within a solid and how these vibrations contribute to the material's heat capacity. According to the model, at low temperatures, the specific heat increases as temperature rises, but at higher temperatures, it levels off. This behavior arises because atoms can only vibrate at certain frequencies, like musical notes, and as temperature increases, more and more vibrations become involved. This model is key in understanding thermal properties in materials physics.
