Modeling the Thermoelectric Properties of Bulk and Nanocomposite Thermoelectric Materials
Thermoelectric materials are materials which are capable of converting heat directly into electricity. They have long been used in specialized fields where high reliability is needed, such as space power generation. Recently, certain nanostructured materials have been fabricated with high thermoelectric properties than those of commercial bulk materials, leading to a renewed interest in thermoe...
متن کاملModel of transport properties of thermoelectric nanocomposite materials
We present a model describing the carrier conductivity and Seebeck coefficient of thermoelectric nanocomposite materials consisting of granular regions. The model is successfully applied to explain relevant experimental data for PbTe nanocomposites. A key factor is the grain potential boundary scattering mechanism. Other mechanisms, such as carrier-acoustic phonon, carrier-nonpolar optical phon...

having conducted the experiment and analysed the data, the researcher computed the groups mean scores and variances for the test relating to the research question. as the final atep, a t-test was conodonted for the hypothesis. as noted earlier, the significance level was determined at .05 and .01 respectively. the observed t-value was higher than the critical t-value at. 5 and .01 levels. conse...
