Electron transport properties of MgB2 in the normal state

We have measured the resistivity and the Seebeck coefficient of a MgB2 sintered sample. The temperature dependence of resistivity is fitted well by a generalized Bloch-Gruneisen equation with a Debye temperature of 1050 K. The Seebeck coefficient is given by the sum of a diffusive and a phonon drag term and the behavior in the temperature region $% Tc
