Our free Lattice (Phonon) Thermal Conductivity Calculator estimates the thermal conductivity (κ) of materials crucial for solid-state physics and materials engineering. Input volumetric specific heat (C), phonon group velocity (v), and mean free path (L) to instantly determine heat transport properties in semiconductors and thermoelectric devices. Optimize thermal management and material design efficiently.
Formula:
The lattice (phonon) thermal conductivity (κ) is typically estimated using the kinetic theory approach:
κ = (1/3) × C × v × L
- κ: Lattice (Phonon) Thermal Conductivity (W/(m·K))
- C: Volumetric Specific Heat Capacity (J/(m³·K))
- v: Average Phonon Group Velocity (m/s)
- L: Phonon Mean Free Path (m)
