Abstract
This study investigates the thermoelectric properties of Pb-doped p-type Bi 0.5Sb 1.5Te 3 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 ( md *), non-degenerate mobility..... More
