In solid-state physics, you are given a thermoelectric material with a known Seebeck coefficient, electrical conductivity, and thermal conductivity. You need to investigate how the thermoelectric properties of this material change with respect to temperature and dopant concentration. What is the optimal dopant concentration that maximizes the thermoelectric figure of merit at a given temperature range?
