We have measured the thermoelectric power of NbSe3 in the temperature range, 10-70 K, where charge-density-wave formation and strongly nonlinear conductivity has been reported. We report the first observation of an electric-field-dependent thermopower. Our results for NbSe3 show that in the presence of an electric field there is an additional negative contribution to the thermopower. Possible mechanisms which may account for this are discussed.
