Insight into Thermoelectric Response of LaCoCrGa Quaternary Heusler alloy for Green Energy Devices

Employing the first-principles simulation packages and post Semi-classical Boltzmann transport theory, the investigation of thermoelectric transport properties of LaCoCrGa Heusler alloy are analyzed. We tried to find the ways of optimizing the thermoelectric response against the chemical potential and its robustness against the pressure variation. The different heat transport coefficients convey the material as n-type with nearly independent nature against the pressure. Understanding the variation against the chemical potential convey that the alloy shows higher peaks with increase in temperature, while as the increase of pressure only shifts the peak towards the higher chemical potential. The information of chemical potential could lead to explore the optimized range for application purposes. The overall strength of the all-physical properties conveys its potential stand for the heat recovery devices as green energy source for future technologies.
