摘要：
我们研究了热电问题，并提出了一个简单的微观机制，提高热电效率。考虑开放的经典遍历台球中粒子和能量的交叉输运。我们发现，在线性响应制度，我们找到所有的传输系数的精确表达式，理想的遍历气体的热电效率可以接近卡诺效率足够复杂的载流子分子。我们的结果清楚地证明了一个简单的数值模拟的洛伦兹气体的粒子与内部旋转自由度。
英文摘要：
We study the problem of thermoelectricity and propose a simple microscopic mechanism for the increase of thermoelectric efficiency. We consider the cross transport of particles and energy in open classical ergodic billiards. We show that, in the linear response regime, where we find exact expressions for all transport coefficients, the thermoelectric efficiency of ideal ergodic gases can approach Carnot efficiency for sufficiently complex charge carrier molecules. Our results are clearly demonstrated with a simple numerical simulation of a Lorentz gas of particles with internal rotational degrees of freedom.
