Thermoelectric materials
The
application
of
such
materials
aims
in
the
conversion
of
waste
heat
into
electric
energy
(Seebeck
effect).
Moreover
these
materials
are
used
as
cooling
modules
in
devices
without
mechanical
parts
(Peltier
effect).
In
our
laboratory
we
form
such
materials
through
physical
and
chemical
growth
methods
such
as:
chemical
vapor
deposition/pack-cementation,
electrodeposition
and
ion
sputtering.
The
obtained
materials
can
be
in
the
form
of
bulk
structures
or
powder
and
have
low
toxicity
and
cost.
The
structural
characterization
is
performed
by
all
the
appropriate
techniques
available
in
our
lab,
while
the
evaluation
of
the
efficiency of final products is accomplished by electric measurements.
