利用通过原子操纵构建的开放式 Fe 纳米畜栏,我们展示了开放量子畜栏中的自我调节 Gd 原子捕获。捕获的 Gd 原子数量完全由围栏的直径决定。量子化可以理解为一个自我调节过程,源于 Gd 原子和开放围栏之间的长程相互作用。我们用开放畜栏阵列说明这种原子捕获可以抑制不需要的统计波动。我们的方法为原子级精度的纳米材料设计和制造开辟了一条潜在途径。
Utilizing open Fe nanocorrals built by atom manipulation, we demonstrate self-regulated Gd atom trapping in open quantum corrals. The number of Gd atoms trapped is exactly determined by the diameter of the corral. The quantization can be understood as a self-regulating process, arising from the long-range interaction between Gd atoms and the open corral. We illustrate with arrays of open corrals that such atom trapping can suppress unwanted statistical fluctuations. Our approach opens a potential pathway for nanomaterial design and fabrication with atomic-level precision.
