The most effective way to realize a cutting-edge figure of meritin thermoelectric materials is to devise a means of strategicallyintegrating the multiple approaches in a single sample. Theelectronic structure engineering tactics can enhance the powerfactor while the thermal conductivity can be minimized by considering the all-length scale hierarchical techniques. However,such synergistic improvements are not easy to apply. Forexample, when extrinsic dopants are introduced to regulatethe carrier density stimulate band convergence, they tend toincrease the electronic thermal conductivity and reduce the figure of merit. Similarly, when nano precipitates are injected toscatter the medium wavelength phonons, the low energycharge carriers produced affect the Seebeck coefficient’s valueadversely. Therefore, the systematic improvement of oneparameter without inducing a deleterious impact on the restis the field’s future research trend.
