| 内容記述 | We propose a new atomistic-scale model (2.429-ML model) for experimentally-observed superstructures of the Si(111)-√7×√3-In surface, using first-principles calculations based on the density-functional theory. It successfully explains the long-range images observed in scanning-tunneling microscopy (STM) experiments, as well as the band structure obtained from angle-resolved photoemission spectroscopy (ARPES) experiments. Our new model is more plausible than the previous 2.4-ML model that only reproduces the ARPES experiment, providing a basis for application studies of this surface. We also show that the arrangement of the bright spots in the STM images can be seen as a beat pattern, i.e., one-dimensional Moire. | |||||||||||
