(a) Zoomed-in STM image of the silicon layer. Besides the brightest protrusions, two other regions showing different contrasts are indicated by the upward and downward triangles. The honeycomb feature is indicated by the black hexagon. (b) Simulated STM image, showing features identical with the experimental results in the same triangles and hexagons. (c) Top view of the relaxed atomic model of the silicene/ Ir (111) configuration.^{[ 73 ]}
