Abstract

We present the results of electrical resistivity, thermoelectric power and thermal conductivity on polycrystalline MgB2 samples. From the analysis of the results we find the Fermi energy EF ¼ 0:8 eV and the electron–phonon coupling constant, ktr, estimated from transport properties, lies in the range 1.25–2.25.
