Strain dependence of the thermoelectric properties of perovskite MgSiO3: A first principles study.

Publication Type: Academic Journal

Source(s): Journal of Applied Physics. 1/14/2023, Vol. 133 Issue 2, p1-7. 7p.

Abstract: Using first-principles density functional theory based approach, we investigate the tunability of the thermoelectric properties of perovskite MgSiO3. We find that the thermoelectric properties are strongly correlated with the electronic structure and c...

Thermoelectric properties of C2P4 monolayer: A first principle study.

Publication Type: Academic Journal

Source(s): Journal of Applied Physics. 1/7/2023, Vol. 133 Issue 1, p1-13. 13p.

Abstract: We have theoretically explored the electronic and thermoelectric properties of the C2P4 monolayer with the interface of density functional theory and semi-classical transport theory. Our calculation shows a high Seebeck coefficient and low electronic t...

Thermoelectric transport properties of orthorhombic RbBaX (X = Sb, Bi) with strong anharmonicity.

Publication Type: Academic Journal

Abstract: The thermoelectric properties of RbBaX (X = Sb, Bi), an anisotropic material with strong anharmonicity, are systematically studied by first-principles calculations, combined with the self-consistent phonon theory and the Boltzmann transport equation. A...

Thermoelectric figure-of-merit from Peltier cooling.

Publication Type: Academic Journal

Source(s): Journal of Applied Physics. 11/7/2022, Vol. 132 Issue 17, p1-5. 5p.

Abstract: We use Peltier cooling to experimentally determine the thermoelectric figure-of-merit of a material, where the maximum temperature depression, ΔTmax, is simply related to Z of a thermocouple. However, for thermocouples comprising good thermoelectric ma...

Thermoelectric properties of Rashba compounds KSnX (X = Sb, Bi).

Publication Type: Academic Journal

Abstract: Here, we have presented the results of the detailed theoretical study of thermoelectric properties of two Rashba compounds KSnSb and KSnBi using first principles calculations based on density functional theory and Boltzmann transport theory taking spin...

Grading studies for efficient thermoelectric devices using combined 1D material and device modeling.

Publication Type: Academic Journal

Source(s): Journal of Applied Physics. 9/21/2022, Vol. 132 Issue 11, p1-7. 7p.

Abstract: The efficiency at which thermoelectric generators (TEGs) can convert heat into electrical energy is governed by the properties of the employed functional materials. For a given thermoelectric (TE) material, efficiency needs to be maximized by adjusting...

Modelling of the Temperature Profile of Heat Sinks for a Thermoelectric Cooler Module.

Publication Type: Academic Journal

Source(s): Nigerian Journal of Technology. May2022, Vol. 41 Issue 3, p429-437. 9p.

Abstract: Thermoelectric refrigeration achieves cooling through Peltier and Seebeck effect. Heat sinks attached to the hot and cold sides of the thermoelectric module help to efficiently dissipates and absorb heat. This research modelled the temperature profile ...
