标题： Effect of incoherent scattering on three-terminal quantum Hall thermoelectrics

摘要： 一个三端导体在量子霍尔效应区域表现出独特的热电和热性能：它可以表现为对称整流器和理想的热二极管。 这些特性依赖于手性边缘通道上的相干传播。 我们研究了通过引入探测端子来破坏相干传播的影响。 结果表明，手性效应不仅能在无相干性的存在下存活，甚至可以在完全无相干性的区域内提高热电性能。 显示英文摘要

摘要： A three-terminal conductor presents peculiar thermoelectric and thermal properties in the quantum Hall regime: it can behave as a symmetric rectifier and as an ideal thermal diode. These properties rely on the coherent propagation along chiral edge channels. We investigate the effect of breaking the coherent propagation by the introduction of a probe terminal. It is shown that chiral effects not only survive the presence of incoherence but they can even improve the thermoelectric performance in the totally incoherent regime.
