Observations of d-band quantum well states are made for atomically uniform Ag films on Fe(100) using angle-resolved photoemission. For increasing film thicknesses, quantum well peaks within the small 4d bandwidth multiply rapidly and merge into a bulklike spectrum at approximately 25 monolayers. An analysis of the peak positions yields a highly accurate bulk band structure of Ag. A very narrow d-band peak width (13 meV) is observed at the band top.
利用角分辨光电子能谱对Fe(100)上原子级均匀的Ag薄膜进行了d带量子阱态的观测。随着薄膜厚度的增加，在小的4d带宽内的量子阱峰迅速倍增，并在约25个单层时合并成类似体材料的光谱。对峰位置的分析得出了高度精确的Ag体带结构。在带顶观察到非常窄的d带峰宽（13毫电子伏特）。
