Silicene on Ag(111): Geometric and electronic structures of a new honeycomb material of Si

Scanning tunnelling spectroscopy and Raman spectroscopy of monolayer silicene on Ag(111)

“…1(c)). The two other structures that also grow at the same time are identified as the (4 × 4) and (√13 × √13 − α) silicene phases in agreement with the structures observed in the temperature range of 230-250°C [5,18,19]. We note that the proportion of the (√13 × √13 − β) phase with respect to the two other phases decreases as the coverage approaches 1 ML.…”

“…Such a quest has led to the successful formation of two-dimensional silicon crystals on a silver surface [1][2][3][4]. Based on the comparison of diffraction patterns, real space imaging and first principles density functional theory (DFT), several atomic phases have been identified, that all have in common a honeycomb structure [5]. In analogy to graphene, these crystals have been coined the name of "silicene".…”

Field-induced diverse quantizations in monolayer and bilayer black phosphorus

“…They have been successfully synthesized by various experimental methods, such as, graphene [4], silicene [5], germanene [6], tinene [7], and transition metal oxides [8]. Such 2D systems are very suitable for studying the novel physical, chemical and material phenomena.…”

Pragmatic Application of Abstract Algebra to Two-Dimensional Lattice Matching

“…Challenges have been made to synthesize these novel materials on solid substrates, to reveal their geometric and electronic structures as well as to bring out the hidden properties by lattice engineering and tailoring of the interfacial couplings [6][7][8][9][10][11][12][13][14]. In these challenges, structure determination is central, which provides solid foundation to figure out their properties and develop device applications.…”
