Preface to ”Materials Processing and Crystal Growth
for Thermoelectrics”
A growing public awareness has resulted in consensus that new technologies for renewable
energy must be realized in the near future. This has lead to a focus on several different solutions
to this problem. Thermoelectrics can play a role in this regard, and is one technology that continues
to be of interest. Thermoelectric devices are especially attractive since they have no moving parts, are
very reliable, and allow for a wide range of applications, from industrial to consumer applications.
In order to efficiently convert energy using thermoelectricity, certain material properties are
desirable. This includes a high electrical conductivity, σ, to maintain high charge current, a high
Seebeck coefficient, S, to maintain a high voltage drop, and a low thermal conductivity, κ, to maintain
the temperature gradient. The performance of a thermoelectric device is characterized by the figure
of merit, a dimensionless parameter defined as ZT = S2σ/κ, where T is the absolute temperature. All
other aspects being equal, materials with larger ZT values result in more efficient thermoelectric
devices. New materials research is therefore essential. It is our hope that the manuscripts contained
in this volume will provide a concise reference to some of the current research in the field of
thermoelectric materials research.
