论文摘要
观察到，在声音 - 形成性散射理论上，在任何维度上的线性色散在理论上规定了恒定的电荷传输分布，这是已知的Boxcar曲线所需的恒定电荷传输分布，以最大程度地提高功绩的热电图。由两个传输差距挤压的线性色散，以通过声子变形在散射下进行优化带宽，然后从理论上讲构成了在实际系统中可能出现的全球最佳定性带结构。
Observation is made that a linear dispersion in any dimension under acoustic-phonon-deformation-potential scattering theoretically prescribes a constant charge transport distribution, required for the boxcar profile known to maximize the thermoelectric figure of merit. A linear dispersion squeezed by two transport gaps for optimized bandwidth under scattering by phonon deformation then theoretically constitutes a globally optimal qualitative band structure that may arise in real systems.
