Debye temperature

Debye temperature is a key concept in solid state physics that describes how a material behaves at different temperatures. It represents the temperature above which the vibrations of atoms in a solid can be treated as classical waves. Below this temperature, atomic vibrations are quantized, meaning they can only take on specific energy levels. The Debye temperature helps predict how heat capacity changes in a solid as it cools down, affecting its thermal properties. Materials with higher Debye temperatures generally have lower heat capacities at low temperatures, indicating they can hold and transfer heat differently compared to those with lower Debye temperatures.
