Thermoelectric properties in gallium telluride-gallium antimonide vacancy compounds
… thermal conductivity, are of great importance in solid state cooling and power generation. Solid solution formation is one effective method to achieve low thermal conductivity by phonon scattering due to mass and strain field fluctuation. This type of scattering is maximized in structures …

Barocaloric effects in barium-dicalcium propionate salts
Fluid refrigerants used in vapour-compression cooling systems such as air conditioners and fridges contribute to environmental damage. Should barium dicalcium organic salts show persistent entropy changes under pressure that are reversible, they may serve as environmentally friendly solid-state …

Nanocomposites as thermoelectric materials
… applications in electric power generation and solid-state cooling. The performance of a thermoelectric device depends on the dimensionless figure of merit (ZT) of the material, defined as ZT = S2o-T / k, where S is the Seebeck coefficient, o is the electrical conductivity, k is the thermal …

Electrocaloric and barocaloric effects in organic materials
… could potentially be exploited in novel solid-state cooling systems that may replace current vapour-compression systems, which are environmentally harmful, noisy, and relatively energy inefficient. In this work, I studied EC effect and BC effects in multicaloric organic materials, which …
