Abstract:
Abstract Thermoelectric (TE) materials are able to generate power from waste heat and thereby provide an alternative source of sustainable energy. Calcium cobaltite is a promising p-type TE oxide because of its intrinsically low thermal conductivity arising from the misfit-layered structure. Its structural framework contains two sub-layers with different incommensurate periodicities, offering different sites for substituting elements; the plate-like grain structure contributes to texture development, thereby providing opportunities to modulate the TE response. In this topical review, we briefl

Abstract:
As demand for energy increases, there will be greater need for more efficient energy generating technologies. Much of the energy lost in current generation systems is through heat. Thermoelectricity provides one way to recover waste heat and convert it into useful energy, but the efficiency of commercially-available thermoelectric devices is relatively low, especially at temperatures approaching 800 C. Therefore, advanced materials for use in high-temperature thermoelectric devices are necessary. This thesis examines the thermoelectric properties of electrospun layered calcium cobaltites. Lay

Perovskite oxides show wide range of applications in the area of magnetism, ferroelectricity, piezoelectricity, thermoelectricity, gas sensing, catalyst development, solid oxide fuel cell, etc. This is due to flexibility in the structure and compositions that can be tuned by specific element doping. In the perovskite oxide (ABO3), large cation (A) is 12 -coordinated and smaller B-cation is 6 coordinated with oxide ions. Oxide materials are considered as better candidates for thermoelectric applications (interconversion of thermal into electrical energy) due to its non-toxicity and thermal stab
