Determination of Electronic Quality Factor, Universal Electrical Conductivity, Effective Mass and Mobility of Charge Carriers of Alloy N-SixGe1-X

The temperature dependences of the electronic quality factor and the universal electrical conductivity of n-type SixGe1-x, as well as the dependences of the Seebeck coefficient on the specific and the universal conductivities, are studied. The effective masses and mobilities of charge carriers are calculated for different temperatures, temperature dependences of the eleqtronic quality factor and the thermoelectric figure of merit are studied. Based on the investigated n-SixGe1-x (x=0.83) together with p-Si0.83Ge0.17, a thermoelectric module was manufactured and its energetic characteristics were studied.
