Thermo electric power measurement of barium oxalate crystals
An attempt is made in the present work to characterize gel grown barium oxalate crystals by Thermo Electric Power (TEP) measurement. Different parameters such as Fermi energy and mode of scattering were calculated. To calculate Fermi energy and scattering parameter of a material, a graph of Seebeck coefficient(S), versus reciprocal of temperature difference (1/ΔT) is plotted. The slope of the graph is - 27.50 mV and intercept is 0.181 mV/K, and hence Fermi energy, EF = 0.028 eV. Scattering parameter has calculated 0.4. The experimental value obtained for A = 2.10 is in well agreement to conclude that the conduction of heat in the material may be due to the lattice or phonons and can be associated with lattice or phonon scattering.
