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
\[\Lambda= \sqrt{\frac{h^2}{2\pi mk_BT}}\]
where
- h is the Planck constant
- m is the mass
- \(k_B\) is the Boltzmann constant
- T is the temperature.
