Abstract
This study investigates the thermoelectric properties of Pb-doped p-type Bi_0.5Sb_1.5Te₃ alloys using the Single Parabolic Band (SPB) model, focusing on optimizing room-temperature performance. We systematically analyze the effects of Pb doping (0, 0.49, 0.65, 0.81, 0.97, and 1.3 at%) on key parameters including density-of-states effective mass (m_d *), non-degenerate mobility..... More

Abstract
Cu₃SbSe₄ is considered a promising thermoelectric material because of its large effective mass and low thermal conductivity, originating from its unique lattice structure. However, Cu₃SbSe₄ has intrinsically low carrier concentration and relatively high electric resistance which limit performance. Recently, a zT improvement in Cu₃SbSe₄ was reported where doping/precipitation is controlled..... 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

Abstract
Environmentally sustainable thermoelectric technologies can be more broadly applied in industries once the performance of thermoelectric materials is improved. Several approaches have been proposed to improve the electronic transport properties of thermoelectric materials. The effects of each approach on the electronic properties can be evaluated by changes in the band..... More

Abstract
One of the most popular routes used to improve the thermoelectric performance of materials is to suppress their lattice thermal conductivities. Thermoelectric performance is characterized by a figure-of-merit zT, which is defined as σS²T/(κ_e + κ_l), where the σ, S, T, κ_e, and κ_l are the electrical conductivity, Seebeck coefficient,.....
