We extract phonon contributions from the transport properties of a (formula presented) single crystal. The temperature dependence of the in-plane resistivity is well explained by the Bloch-Grüneisen formula with the Debye temperature (formula presented) taking into account an additional contribution of the (formula presented) phonon mode (formula presented) In the thermoelectric power, we find a phonon drag peak around 70 K, which gives a consistent estimation of (formula presented) with the resistivity result. The pressure dependence of the in-plane resistivity reveals a major contribution of the (formula presented) phonon mode to superconductivity.
