提出了一种半导体界面原子分辨率成分映射的新策略。图像可以直接解释到 10% 以内,以提供逐列的成分信息,其灵敏度接近卢瑟福散射截面。我们应用该方法获得了超薄 (Si{sub m}Ge{sub n}){sub p} 超晶格中界面有序的第一张原子分辨率图像,并将结果归因于 (2 {times} 1) 和 (1 {times} 2) 重建表面上的生长。 13 个参考文献,7 个图。
A new strategy for atomic resolution compositional mapping at semiconductor interfaces is presented. Images can be interpreted directly to within 10% to give column-by-column compositional information with a sensitivity approaching Rutherford scattering cross sections. We apply the method to obtain the first atomic resolution images of interfacial ordering in ultrathin (Si{sub m}Ge{sub n}){sub p} superlattices and attribute the results to growth on (2 {times} 1) and (1 {times} 2) reconstructed surfaces. 13 refs., 7 figs.
