In recent years, the progress of miniaturization of electronic devices stimulates a growing interest in low dimensional materials. Among them, silicene, the allotrope of silicon equivalent of graphene, has attracted increasing attention owing to its superior electronic properties. Silicene has a honeycomb structure similar to graphene. The band structure of silicene, which forms ‘Dirac cone’ at the symmetric point K in the reciprocal space, indicates that the charge carriers in silicene sheets behave like massless Dirac fermions.
In this presentation, the high-resolution AFM imaging of silicene on Ag(111) and investigation of Si nanoribbons on Ag(111) by STM and AFM will be talked about.
