We give a detailed discussion of the quantum interference effect transistor (QuIET), a proposed device which exploits the interference between electron paths through aromatic molecules to modulate the current flow. In the off state, perfect destructive interference stemming from the molecular symmetry blocks the current, while in the on state, the current is allowed to flow by locally introducing either decoherence or elastic scattering. Details of a model calculation demonstrating the efficacy of the QuIET are presented, and various fabrication scenarios are proposed, including the possibility of using conducting polymers to connect the QuIET with multiple leads.
我们详细讨论了量子干涉效应晶体管（QuIET），这是一种提议的器件，它利用电子通过芳香分子的路径之间的干涉来调制电流。在关态下，源于分子对称性的完全相消干涉会阻断电流，而在开态下，通过局部引入退相干或弹性散射使电流能够流动。给出了一个证明QuIET有效性的模型计算细节，并提出了各种制造方案，包括使用导电聚合物将QuIET与多个引线连接的可能性。
