Abstract:
|
Nanocomposites are highly promising
materials to enhance the efficiency of current thermoelectric
devices. A straightforward and at the same time
highly versatile and controllable approach to produce
nanocomposites is the assembly of solution-processed
nanocrystal building blocks. The convenience of this
bottom-up approach to produce nanocomposites with
homogeneous phase distributions and adjustable composition
is demonstrated here by blending Ag2Te and
PbTe colloidal nanocrystals to form Ag2Te–PbTe bulk
nanocomposites. The thermoelectric properties of these
nanocomposites are analyzed in the temperature range
from 300 to 700 K. The evolution of their electrical
conductivity and Seebeck coefficient is discussed in
terms of the blend composition and the characteristics of
the constituent materials. |
