Abstract Silicene, a silicon analog of graphene, holds promise for next-generation electronics due to its tunable bandgap and larger spin-orbit coupling. Despite extensive efforts to synthesize and characterize silicene on metal substrates, bond-resolved imaging of its atomic structure has remained elusive. Here, we report the fabrication and bond-resolved characterization of silicene on Au(111) substrate. Three silicene phases tuned by surface reconstruction and annealing temperatures are achieved. Using CO-terminated scanning tunneling microscopy (STM) tips, we resolve these silicene phases with atomic precision, determining their bond lengths, local strain, and geometric configurations. Furthermore, we correlate these structural features with their electronic properties, revealing the effect of strain and substrate interactions on the electronic properties of silicene. This work establishes silicene's intrinsic bonding topology and resolves longstanding controversies in silicene research.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
