The thermoelectric efficiency of a thermal machine consisting of a triangular graphene nano-junction connected to three electrodes in the linear response regime is studied. Using the Onsager formalism and a combination of semi-empirical tight-binding calculations as well as Green's function theory, the efficiency at maximum output power which can be written in terms of generalized figures of merit is investigated. The results for a set temperature and chemical potential parameters have shown that adding a third terminal improves the efficiency at maximum output power compared to the two-terminal setup.
研究了由连接到三个电极的三角形石墨烯纳结组成的热机在线性响应区的热电效率。使用昂萨格形式主义和半经验紧束缚计算以及格林函数理论，以广义优值的形式研究了最大输出功率时的效率。对于一组温度和化学势参数的结果表明，与两终端设置相比，添加第三个终端可以提高最大输出功率时的效率。
