We have examined the electrical transport properties of densified LaOBiS2-xSex, which constitutes a new family of thermoelectric materials. The power factor increases with increasing concentration of Se, i.e., Se substitution leads to an enhanced electrical conductivity, without suppression of the Seebeck coefficient. Hall measurements reveal that the carrier mobility increases with decreasing carrier concentration as Se doping, which is responsible for the low electrical resistivity and large absolute values of the Seebeck coefficient in the system.
