摘要

我们在这里提出了一种利用局域取代杂质探测三角形石墨烯量子点[n]三角烯中简并壳层波函数的方法。我们用aza-[n]三角烯的例子证明了它的适用性。利用全碳[n]三角烯简并态的解析解作为含氮杂质的[n]三角烯的基础，我们预测了含氮杂质时零能壳层的结构。我们表明，杂质允许探测简并壳层在其所在的碳位上的波函数。我们通过与紧束缚和从头算的比较以及与实验的比较证实了我们的预测。

Probing the zero energy shell wave functions of triangular graphene quantum dots with broken sublattice symmetry using a localized impurity

We present here a method of probing the wave functions of a degenerate shell in a triangular graphene quantum dot, [n]triangulene, using a localized substitutional impurity. We demonstrate its applicability to the example of aza-[n]triangulenes. Using the analytical solution for degenerate states of an all-carbon [n]triangulene as a basis for a [n]triangulene containing a nitrogen impurity, we predict the structure of the zero energy shell in the presence of this impurity. We show that the impurity allows probing of the wave functions of a degenerate shell on a carbon site where it is located. We confirm our predictions by a comparison with the tight-binding and ab-initio calculation as well as with experiment.

期刊介绍： Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged. A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions. The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
