| Abstract: | Coupled electron-hole (e-h) Boltzmann equations are applied to evaluate the resistivity  and Hall coefficientR
H for a two-band model system with e-h, impurity, and phonon scatterings. We show that the anomalous temperature dependences = T andR
H
–1
= T observed on YBaCuO compounds can be obtained by assuming a special two-band model in which the e-h scattering is responsible for the resistivity and the chemical potential varies linearly with temperature. |
