Query: Thermoelectric propertie of Ge based electron crystal phonon glass
  materials   We report on the elaboration of germanium manganese nanostructured thin films
and the measurement of their thermoelectric properties. We investigate the
growth of Ge:Mn layers along with a thorough structural characterization of
this materials at the nanoscale. The room temperature thermoelectric properties
of these layers containing spherical inclusions are discussed regarding their
potential as a model of "electron crystal phonon glass material". We show that
the thermal conductivity can be decreased by a factor of 30, even if the
electronic properties can be conserved as in the bulk. The thermoelectric
performance ZT of such material is as high as 0.15 making them a promising
thermoelectric p-type material for Ge related application.
