论文摘要
表面化学产生原子精确的纳米结构的力量为推进量子技术领域提供了有趣的机会。通过单独定位原子或分子来构建人工电子晶格的策略导致精确量身定制的结构，但缺乏结构鲁棒性。在这里，利用BR原子在贵金属表面上的牢固键合的优势，我们报告了通过在预热的AU（111）表面上己二酰苯分子的去盐化来产生稳定的量子柱。副产物，BR Adatoms限制在新的表面重建模式中，并将平均大小为3.7+-0.1 nm的纳米孔聚集，由于散射电子波的干扰，在每个柱子内部产生了原子轨道样的量子共振状态。值得注意的是，原子轨道可以杂交具有不同的键合和抗键状态的分子样轨道。我们的研究开辟了一条途径，以高产和稳健性制造量子结构。
The power of surface chemistry to create atomically precise nanoarchitectures offers intriguing opportunities to advance the field of quantum technology. Strategies for building artificial electronic lattices by individually positioning atoms or molecules result in precisely tailored structures but lack structural robustness. Here, taking the advantage of strong bonding of Br atoms on noble metal surfaces, we report the production of stable quantum corrals by dehalogenation of hexabromobenzene molecules on a preheated Au(111) surface. The byproducts, Br adatoms, are confined within a new surface reconstruction pattern and aggregate into nanopores with an average size of 3.7+-0.1 nm, which create atomic orbital-like quantum resonance states inside each corral due to the interference of scattered electron waves. Remarkably, the atomic orbitals can be hybridized into molecular-like orbitals with distinct bonding and anti-bonding states. Our study opens up an avenue to fabricate quantum structures with high yield and superior robustness.
