High pressure transport properties of pure ytterbium in the metallic bcc phase

Transport properties of pure ytterbium have been measured under high pressure, up to 91 kbar. The thermoelectric power in the fcc phase at 31 kbar is typical of an n-type semiconductor. The resistivity and the thermoelectric power could be determined between 22 and 91 kbar in the metallic bcc phase. In this pressure range, the electron-phonon interaction is predominant in the transport properties. Both resistivity and thermoelectric power exhibit an increase of the Debye temperature by a factor 1.5
