Two Thermoelectric Materials: Thermoelectric Properties of SnTe-SnSe and Synthesis of Skutterudite Na1+xFe4P12
This thesis examines two different types of thermoelectric materials, compounds that can convert heat energy into electrical energy. First, Stevens et al. synthesized a two-phase SnTe- SnSe system and analyzed its thermoelectric properties. It was determined that the two-phase nature of the system contributed to a reduced thermal conductivity and to enhanced thermoelectric performance over that of one-phase SnTe. Second, Liu et al. studied the effects of heating time and temperature on the synthesis of Na1+xFe4P12, a filled skutterudite. X-ray diffraction experiments revealed that the reaction conditions affect the directional growth of crystalline ‘whiskers.’ The x-ray spectra also gave insight into the possible reaction scheme for the formation of the crystal.
