利用角分辨光电子能谱研究了Si(557)衬底上单层覆盖银纳米线的电子结构。费米表面映射揭示了二维(2D)银诱导的电子口袋,转移到更高的结合能的n型掺杂的步骤边缘。1 ML Ag/Si(557)系统的电子结构在费米能级附近表现出额外的2D金属态,这可能源于衬底诱导的周期性。通过考虑限制潜力和电子相干长度,我们调和似乎相互冲突的观点,在这个系统中探测的光电子能谱的维度,和分散体的集体激发检测到的电子能量损失谱。
We investigate the electronic structure of silver nanowires at 1 monolayer (ML) Ag coverage on a vicinal Si (557) substrate by angle-resolved photoemission spectroscopy. Fermi surface mapping reveals two-dimensional (2D) Ag-induced electron pockets, which shift to higher binding energies by n-type doping of the step edges. The electronic structure of the 1 ML Ag/Si (557) system exhibits additional 2D metallic states near the Fermi level, which may originate from substrate induced periodicities. By considering the confining potential and electronic coherence length we reconcile the seemingly conflicting views of the dimensionality in this system probed by photoemission spectroscopy, and the dispersion of collective excitations as detected by electron energy loss spectroscopy.
