摘要

We have measured the thermoelectric power S and resistivity ρ of Mg1-xAlxB2. S is positive and increases linearly with temperature above the superconducting transition temperature Tc. Deviations from the linear dependence appear at higher temperature, T> T0≈ 160 K. Tc and To both decrease with Al doping whereas the slope of S(T) in the linear range increases with the Al content. The data are discussed in terms of doping-induced changes of the Fermi surface and the density of states at the Fermi level.
