# Lattice (Phonon) Thermal Conductivity Calculator

The characteristic of the material to conduct heat is called as the thermal conductivity. Calculate the lattice thermal conductivity of the phonon gas based on the heat capacity of the lattice, volume, effective speed of the sound, mean free path of the phonon.
Thermal conductivity in amorphous and crystalline dielectric solids happens by way of elastic vibrations of the lattice (phonons).

#### Formula:

λ=(1/3)*(C_{v}/v_{s})l
**Where,**
λ = Thermal conductivity
C_{v} = Lattice heat capacity
V = Volume
v_{s} = Effective sound speed
l = Phonon mean free path
