In their research, the team demonstrates that the empirical relationship between the Seebeck coefficient and electrical conductivity (S-σ) can actually be modified through controlled carrier doping. An illustration of the doping technique used to form linkages (red) between PBTTT''s crystalline parts (blue rectangles).
Based on the dependence of the Seebeck coefficient on the carrier concentration, the SSRS sample exhibits the highest value, conceivably due to the high resistivity as shown in Fig. 5a. Among the samples prepared with SPS, the sample prepared at 1200 C exhibits a slightly larger Seebeck coefficient than that of the sample prepared at 900 C.
In this study, the effect of nitrogen (N) doping and microstructural changes on the electrical and thermal properties of silicon carbide (SiC) were investigated.

features, the Seebeck coefficient adds the decisive parameter to fully describe datasets within a resonant tunneling model. The setup provides further potential of controlling additional parameters as it is optically fully transparent. It also allows for nearly arbitrary
Thermal expansion is the tendency of matter to change its shape, area, volume, and density in response to a change in temperature, usually not including phase transitions.[1] Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, molecules begin to vibrate and move more, usually
