Quantum devices depend on addressable elements, which can be modified separately and in their mutual interaction. Self-assembly at surfaces, for example, formation of a porous (metal-) organic network, provides an ideal way to manufacture arrays of identical quantum boxes, arising in this case from the confinement of the electronic (Shockley) surface state within the pores. We show that the electronic quantum box state as well as the interbox coupling can be modified locally to a varying extent by a selective choice of adsorbates, here C, interacting with the barrier. In view of the wealth of differently acting adsorbates, this approach allows for engineering quantum states in on-surface network architectures.
量子器件依赖于可寻址元素，这些元素可以单独修改，并在它们的相互作用中进行修改。例如，表面的自组装，即形成多孔（金属）有机网络，提供了一种理想的方法来制造相同的量子盒阵列，在这种情况下，量子盒阵列是由电子（Shockley）表面态在孔内的限制产生的。我们表明，通过选择性地选择与势垒相互作用的吸附剂（这里是 C），可以在局部范围内在一定程度上对电子量子盒态和盒间耦合进行修改。考虑到作用方式不同的吸附剂种类繁多，这种方法允许在表面网络结构中设计量子态。
