0.2 ML of silicon deposited on NaCl/Ag(110) at room temperature. (a) LEED diffraction pattern showing a (4 × 1) in blue and (2 × 5) in red periodicities assigned to NaCl/Ag(110) surface and silicene/Ag(110) NRs, respectively. (b) STM image (12.5 × 12.5 nm², U = –1 V, I = 1 nA) showing silicene NRs and a NaCl island (c) STM image (5.5 × 5.5 nm², U = –1 V, I = 0,8 nA) showing accumulation of Si atoms on the NaCl island.
