Abstract
By combining formulae known from the literature that relate thermoelectric parameters, the expression n ≅ 1.13·1019eSr–2/rH(eSr–2–0.17) is obtained. That is, the concentration of charge carriers can be determined using the Hall resistance (rH) and reduced Seebeck coefficient. Since these two parameters are calculated using the Seebeck coefficient (S), this coefficient is sufficient to determine the concentration. To demonstrate the use of the obtained new formula, experimental data on silicon-germanium thermoelectric are discussed.
