| Abstract Scope |
Solubility of dopant species is an important materials property which determines its potential for optimizing its thermoelectric figure of merit. Experimental reports often conclude reaching the solubility limit as soon as any impurity phases are observed. However, this approach does not necessarily ensure reaching the actual maximum solubility in compounds. As a result, solubility limit in many thermoelectric materials were mistakenly underestimated in the past, thereby unknowingly discouraging further attempts and delaying the realization of better and reproducible thermoelectric performance. In this talk, we summarize in simple graphical guidelines --- rooted in thermodynamics --- how the maximum dopant solubility can be concluded using the stoichiometry of the impurity phase observed. |
