通过低温扫描隧道显微镜和光谱学，并结合高达 10 T 的磁场中的输运测量，研究了 InSb 劈裂表面处吸附物诱导的二维电子系统。从空间平均态密度获得的潜在无序的大小与从 Shubnikov-de Haas 振荡分析推论的一致。
An adsorbate-induced two-dimensional electron system at cleaved surfaces of InSb is investigated by low-temperature scanning tunneling microscope and spectroscopy combined with transport measurements in magnetic fields up to 10 T. The magnitude of the potential disorder obtained from the spatially averaged density of states agrees with that deduced from the analysis of the Shubnikov-de Haas oscillations.
