New Structural Model for the Si(331)-(12×1) Surface Reconstruction
Abstract
A new structural model for the Si(331)-(12×1) surface reconstruction is proposed. Based on scanning tunneling microscopy images of unprecedented resolution, low-energy electron diffraction data, and first-principles total-energy calculations, we demonstrate that the reconstructed Si(331) surface shares the same elementary building blocks as the Si(110)-(16×2) surface, establishing the pentamer as a universal building block for complex silicon surface reconstructions.
