TE Tutorial
Mutual interaction of heat and electricity is the origin of Seebeck and
Peltier effects which are used in thermocouples for temperature sensing and
in thermoelectric modules for solid-state refrigeration or power
generation. An overview of recent advances in bulk and thin film
thermoelectric materials and devices will be given. Material optimization
is focused on reducing the lattice thermal conductivity without reducing
electrical conductivity and/or increase the Seebeck coefficient. Recent
development in skutterudites, clathrates, half-heusler alloys and oxides
will be reviewed. Nanoscale engineering of materials gives the opportunity
to modify the fundamental thermoelectric transport properties beyond what
can be achieved in bulk materials. These include quantum confinement due to
wave nature of carriers and interface effects such as thermionic emission
and evaporative cooling at heterostructures. Significant improvements based
on superlattices and embedded quantum dots have been achieved. Bipolar
thermoelectric effects will be introduced. They could be used for internal
cooling of electronic and optoelectronic devices. Finally fundamental
efficiency limitations of thermoelectric energy converters and practical
system optimization will be discussed.
