Abstract
This study investigates the thermoelectric properties of Fe_1-xCo_xSe₂ (x = 0, 0.25, 0.5, 0.75, and 1) alloys using theoretical modeling approaches. The Single Parabolic Band (SPB) model was employed to calculate band parameters such as density-of-states effective mass (m_d*), non-degenerate mobility (μ₀), weighted mobility (μ_w), and B-factor. As the alloying..... More

Abstract
Bi₂Te₃ shows high thermoelectric performance near room temperature, making it the most widely used material in thermoelectric cooling applications. Cu doping has been found to be effective in improving the thermoelectric performance of Bi₂Te₃. However, due to the problem of easy migration of Cu ions, the stability of Cu-doped Bi₂Te₃..... More

Abstract
SnSe is a promising thermoelectric material due to its low toxicity, low thermal conductivity, and multiple valence band structures, which are ideal for high electronic transport properties. The multiple valence band structure has attracted many attempts to engineer the carrier concentration of the SnSe via doping, to place its fermi..... More
