Thermoelectric Effect in High-T_c Superconductors: the Role of Density of States Fluctuations

We study the effect of the density of states (DOS) fluctuations on the thermoelectric coefficient of superconductor above critical temperature. It is shown that in the isotropic case it is the DOS contribution which gives rise to the leading correction to thermoelectric coefficient in spite of previous results where the only Aslamazov-Larkin term was taken into account. This conclusion is valid for an arbitrary impurity concentration.
