Abstract : Using Langevin simulations, we numerically study the influence of temperature to the dynamics of driven two-dimensional colloids on a disordered substrate. With decreasing temperature, the result shows a dynamic phase transition from the moving liquid to the moving smectic at high driving forces. A peak appears in the dynamically-critical driving force across the transition, accompanied by a clear cross of the curves of velocity-force dependence.
