Nanoscale rectifiers are known to have significant nanoelectronic and nanoheatronic applications. In the present work we theoretically analyze rectifying properties of a junction including a couple of quantum dots asymmetrically coupled to the electrodes. The charge and heat current rectification in the system is controlled by the dots occupation numbers and interdot Coulomb interactions. We examine the dependencies of the rectification ratio on the electron energy levels on the dots, on the intensity of electron-electron interactions, on the gate and bias voltages and on the thermal gradients applied across the system. It is shown that the considered double-dot system possesses significant potentialities as a common as well as a heat diod.

在库仑封锁范围内通过双点系统进行电荷和热流整流


众所周知，纳米级整流器具有重要的纳米电子和纳米热电子应用。在目前的工作中，我们从理论上分析了包含一对不对称耦合到电极的量子点的结的整流特性。系统中的电荷和热流整流由点占据数和点间库仑相互作用控制。我们研究了整流比对点上电子能级、电子-电子相互作用强度、栅极电压和偏置电压以及整个系统施加的热梯度的依赖性。结果表明，所考虑的双点系统作为普通二极管和热二极管具有巨大的潜力。
