Abstract ： to date, some confusion exists in the literature concerning the employment of the diffusion driving force and the calculation of the diffusion velocity for the gas species in a two-temperature (2-T) plasma. In this letter, a derivation is presented concerning the species diffusion driving force and diffusion velocity under 2-T plasma conditions. Expressions for the ambipolar diffusion coefficients and the electric conductivity of the 2-T plasma are also given.
