In this work we have performed HEX-NEMD simulations to calculate thermal diffusion factor (TDF) for binary mixtures of square well particles for a wide range of diameter ratios, well depth ratios and well width ratios for a fixed reduced density and temperature. The results show that dependence of TDF to the potential parameters is resembled to the Lennard-Jonnes mixtures. The TDF decreases with diameter ratio. However, TDF increases as the ratios of well depth, well width and mass of two particles become larger than one.
