1. We investigate the thermoelectric properties in different materials by tuning the thermoelectric power considering decoupling mechanism of charge.-heat and other quantities.
2. We have developed strategies to include electron-electron, phonon-phonon relaxation times which can be considered as descriptors. These can be calculated by knowing elastic constant (cβ) , deformation potential constant (Ecβ), , group velocity of phonon(vg) etc.
3. With all these, we can estimate relaxation time for electron and phonon and thereby mobility and conductivity of charge carriers, phonon conductivity, Seebeck coefficient and power factor.
4. We estimate the figure of merit (zT) of. thermoelectric materials and through appropriate descriptors, the microscopic properties behind the magnitude of zT and its regulation.
