Thermoelectric transport due to the motion of free unbound vortices above the Kosterlitz-Thouless transition temperature is considered. It is shown that the Magnus force, which appears under the influence of the temperature gradient, leads to a nonzero thermopower at a temperature above the Kosterlitz-Thouless transition temperature [ital T][sub KT], but below the mean-field (Ginzburg-Landau) critical temperature [ital T][sub GL]. The exponential inverse-square-root reduced-temperature dependence of the thermopower above [ital T][sub KT] is predicted with a consequent broadening of the superconducting transition detected by means of thermopower measurements. The case of the clean superconductor is analyzed.
