The structural evolution of planar Si clusters and the nucleation mechanism of silicene in the initial stages of silicene epitaxial growth on a Ag(111) surface are studied by using ab initio calculations and two-dimensional nucleation theory. The ground-state SiN clusters (1 ≤ N ≤ 25) on the Ag(111) surface are found to undergo a significant structural transition from non-hexagonal plane structures to fully-hexagonal ones at N = 22, which is a crucial step for growing a high-quality silicene…

Temperature and coverage effects on the stability of epitaxial silicene on Ag(111) surfaces
Construction of 2D atomic crystals on transition metal surfaces: graphene, silicene, and hafnene.
TLDR
The synthesis and structures of graphene on Ru(0001) and Pt(111), silicene on Ag(111) and Ir( 111) and the honeycomb hafnium lattice on Ir(110) are reviewed and will shine light on the design and synthesis of new 2D crystals with novel properties.
Nucleation and temperature-driven phase transitions of silicene superstructures on Ag(1 1 1).
TLDR
This work has shown that post-deposition annealing temperature determines the self-organization of silicene domains even in the submonolayer coverage regime and consecutive transitions between silicenes with different periodicity.
Growth mechanism and modification of electronic and magnetic properties of silicene
Silicene, a monolayer of silicon atoms arranged in a honeycomb lattice, has been undergoing rapid development in recent years due to its superior electronic properties and its compatibility with…
Unveiling the atomic structure and electronic properties of atomically thin boron sheets on an Ag(111) surface.
TLDR
The results reveal that there exist three energetically favorable borophene structures on the Ag(111) surface and their simulated STM images are in good agreement with experimental results, suggesting the coexistence of boron phases during the growth.
Heterogeneous Nucleation of Colloidal Crystals on a Glass Substrate with Depletion Attraction.
TLDR
The heterogeneous nucleation of colloidal crystals with attractive interactions has been investigated via in situ observations and it is concluded that the ΔG of q-2D nuclei is smaller than of monolayer nuclei, provided that the same number of particles are used, which explains the experimental result.
Computational Studies of Silicene on Silver Surfaces
Silicon bulk presents a strong preference for sp 3 hybridization and hence will not form 2D materials spontaneously. Standalone silicene does not exist, however, theoretical studies have predicted…
Symmetry breaking in semiconductor nanocrystals via kinetic-controlled surface diffusion: a strategy for manipulating the junction structure.
TLDR
A robust approach is reported for breaking the symmetry of the CdS lattice and obtaining high-quality C dS ultrathin monopods, bipods, tripods, and tetrapods and showing the highest photocatalytic activity.

In situ low-temperature scanning tunneling microscopy is used to reveal the graphene growth intermediates at different stages via thermal decomposition of methane on Cu(111) and it is clearly demonstrated that various carbon clusters, including carbon dimers, carbon rectangles, and 'zigzag' and 'armchair'-like carbon chains are the actual growth intermediate prior to the graphene formation.
