The discovery of carbon fullerene cages and their solids opened a new avenue to build
materials from stable cage clusters as “artificial atoms” or “superatoms” instead of atoms …

The use of porous silicon (PSi) as a sensor for detection of various analytes is reviewed. The
optical or electrical properties of PSi are key sensing parameters that have been used in …

Scanning tunneling microscopy (STM) and ab initio calculations based on density functional
theory (DFT) were used to study the self-aligned silicon nanoribbons on Ag (110) with …

In this Colloquium the theory of silicon nanowires is reviewed. Nanowires with diameters
below 10 nm are the focus, where quantum effects become important and the properties …

In this Communication, we report fabrication of ultrabright water-dispersible silicon
nanoparticles (SiNPs) with quantum yields (QYs) up to 75% through a novelly designed …

Using ab initio methods, we have investigated the structures and stabilities of SiN clusters
(N≤ 24) on Ag (111) surface as the initial stage of silicene growth. Unlike the dome-shaped …

Silicon photonics is no longer an emerging field of research and technology but a present
reality with commercial products available on the market, where low‐dimensional silicon …

We present a novel synthesis of ligand-free colloidal silicon nanocrystals (Si-NCs) that
exhibits efficient photoluminescence (PL) in a wide energy range (0.85–1.8 eV) overcoming …

Silicene, a monolayer of silicon atoms tightly packed into a two-dimensional honeycomb
lattice, is the challenging hypothetical reflection in the silicon realm of graphene, a one-atom …

In this paper, we discuss the validity of the band structure concept in silicon nanocrystals a
few nanometers in size. We introduce a general method which allows reconstruction of a …
