The thermal de Broglie wavelength is roughly the average de Broglie wavelength of the gas particles in an ideal gas at the specified temperature. It is defined as
\[\Lambda= \sqrt{\frac{h^2}{2\pi mk_BT}} \nonumber\]
where
- \(h\) is the Planck constant
- \(m\) is the mass
- \(k_B\) is the Boltzmann constant
- \(T\) is the temperature.
