Abstract
En 中文
• Pisarenko formula demonstrated to be applicable beyond the non-degenerate semiconductor limit. • Thermopower value of 150 µV K-1 is identified as threshold for accurate effective mass estimation. • α-ln σ plot proposed as a tool for carrier transport analysis. • Analytical prediction of maximum power factor from weighted mobility is demonstrated.
