Can Theory Help in the Search for Better Thermoelectric Materials?,ll be used for energy recovery from the exhaust of the engines with internal combustion, increasing fuel efficiency. This can be achieved if we find a reasonably priced thermoelectric material whose performance is increased by a factor of four.

New Bulk Materials for Thermoelectric Applications: Synthetic Strategies Based On Phase Homologies,electric power (S) and low thermal conductivity (κ) in the same material..These properties define the thermoelectric figure of merit ZT = (S.|ò/k)T; where T is the temperature. The S.s product is often called the power factor. All σ, S and κ are transport quantities and therefore are determined by t

Boron Carbides: Unconventional High-Temperature Thermoelectrics, cage-like structure whose twelve atoms occupy the vertices of an icosahedron. Strong covalent bonds link icosahedra to one another. As a result, boron carbides are very stiff, hard solids whose melting temperatures exceed 2600K. Boron carbides have long been used in applications such as lightweight

Clathrate Thermoelectrics,attice there is not enough space to hold Sr atoms between the Ge atoms, for example. The presence of these “guests” induces a change in the Ge clathrate to a more open structure: the clathrate structure. These types of “open structured” compounds have unique properties that are of interest for therm
