Abstract: Within the t - J model, the heat transport of electron-doped cobaltates is studied based on the fermion-spin theory. It is shown that the temperature-dependent thermal conductivity is characterized by the low-temperature peak located at a finite temperature. The thermal conductivity increases monotonously with increasing temperature at low-temperatures T <0.1 J , and then decreases with increasing temperature for higher temperatures T >0.1 J , in qualitative agreement with experimental result observed from Na x CoO 2 .
