Remarks:
Electrical conductivity
; and Seebeck
coefficient
d are
measured by using
aZEM-lapparatus
(Japan
Vacuum
Tech) in the
temperature
range
from 300
to
500
K.
The thermal conductivity
r
is
obtained
ftom the
measured thermal diffusivity
D,
Specific
heat
Q
and density d
according
to the
relationship
n
=
DxCpxd.
Thermal diffusivity
and specific
heat
are
determined using a
laser
flash method
(NETZSCH:LFA457)
and a
power-compensation
differential
scanning
calorimeter
(TA:DSCQ20), respectively. All
measurements
are
performed
in
the
temperature
range from 300 to
500
K.
