将分子晶体管用作热泵

Operating molecular transistors as heat pumps

D. F. Martinez, Bambi Hu

摘要:

我们研究了由两个储层和一个栅电极组成的类晶体管器件中的热传输,两个储层之间连接着一个弹道电子一维系统,并与激光场相互作用。我们推导出一个简单的方法的热通量方程的Floquet-Green算子的系统。作为一个案例,我们研究了一个两能级晶体管,发现激光场可以产生一个净热流的水库之一。该流动的方向由栅极电压决定。我们研究数值的依赖性,这个热泵系统的相关参数,并表明,有一个最低温度低于它不工作。

英文摘要:

We study heat transport in transistor-like devices composed of two reservoirs and a gate electrode, with a ballistic electronic one-dimensional system connected between the two reservoirs and interacting with a laser field. We derive in a simple way an equation for the heat flux in terms of the Floquet-Green operator of the system. As a case example, we investigate a two-level transistor and find that the laser field can produce a net heat flow out of either one of the reservoirs. The direction of this flow is determined by the gate voltage. We study numerically the dependence of this heat-pump on the relevant parameters of the system and show that there is a minimum temperature below which it does not operate.
