The NATO sponsored Advanced Research Workshop on â€œProperties and Applications of Thermoelectric Materialsâ€ took place on the Croatian island of Hvar over the period 20-26 September, 2008. This subject has attracted renewed interest as concerns with the efficient use of energy resources, and the minimization of environmental damage, have become important current issues. There has been the recognition that thermoelectric devices could play a role in generating electricity from waste heat, enabling cooling via refrigerators with no moving parts, and many other more specialized applications. The main problem in realizing this ambition is the rather low efficiency of such devices for general applications. The workshop addressed that problem by reviewing the latest experimental and theoretical work in this field and by exploring various strategies that might increase the efficiency of thermoelectric devices. A measure of the potential of a particular material for an efficient thermoelectric device is the figure of merit ZT. This dimensionless ratio depends on the electronic conductivity, the total thermal conductivity and the thermopower (Seebeck coefficient) of the material.
