New Directions for Low-Dimensional Thermoelectric Materials
Providing a sustainable supply of energy to the world’s population will become a major societal problem for the 21st century as fossil fuel supplies decrease and world demand increases. Thermoelectric phenomena, which involve the conversion between thermal and electrical energy, and provide a method for heating and cooling materials, are expected to play an increasingly important role in meetin...
متن کاملNew Thermoelectric Materials and New Applications
Thermoelectricity in general is of strong scientific and technological interest due to its application possibilities ranging from clean energy to photon sensing devices. Recent developments in theoretical studies on t he thermoelectric effects, as well as the newly discovered thermoelectric materials provide new opportunities for wide applications. One type of these materials is based on the st...
متن کاملTheoretical and experimental search for ZnSb-based thermoelectric materials.
We report a combined theoretical and experimental search for thermoelectric materials based on semiconducting zinc antimony. Influence of three new doping elements (sodium, potassium and boron) on the electronic properties was investigated as well as the carrier concentration and temperature dependence of the thermoelectric coefficients obtained through density-functional calculations and Boltz...
متن کاملOn the Lorenz number of multi-band materials
There are many exotic scenarios where the Lorenz number of the Wiedemann-Franz law is known to deviate from expected values. However, in conventional semiconductor systems, it is assumed to vary between the values of ∼1.49 × 10−8 W K−2 for nondegenerate semiconductors and ∼2.45 × 10−8 W K−2 for degenerate semiconductors or metals. Knowledge of the Lorenz number is important in many situations, ...
متن کاملLow Dimensional Organic Compounds as Promising Thermoelectric Materials
The thermoelectric properties of quasi-one-dimensional (Q1D) organic crystals with p-type conduction band are studied. Two main electron-phonon interaction mechanisms and carriers scattering on impurities are taken into account. The relaxation time as a function of carrier energy is analyzed for different values of crystal parameters. It is shown that under certain conditions, when the interfer...
