Silicon quantum dots (SiQDs) hold great promise for many future technologies. Silicon is
already at the core of photovoltaics and microelectronics, and SiQDs are capable of efficient …

Silicon nanocrystals (NCs) represent one of the most promising material systems for light
emission applications in microphotonics. In recent years, several groups have reported on …

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 …

We demonstrate the formation of a new type of surfactant-free colloidal silicon nanocrystal
(Si-NC). The characteristic structural feature of the Si-NCs is simultaneous doping of …

Abstract Si nanocrystals (Si-NCs) with extremely heavily B-and P-doped shells are
developed and their structural and optical properties are studied. Unlike conventional Si …

Size dependence of the boron (B) acceptor and phosphorus (P) donor levels of silicon (Si)
nanocrystals (NCs) measured from the vacuum level was obtained in a very wide size range …

In this work we aim at understanding the effect of n-and p-type substitutional doping in the
case of matrix-embedded and freestanding Si nanocrystals. By means of ab initio …

We present tight-binding calculations in the random-phase approximation of the optical
response of Silicon nanocrystals (Si NCs) ideally doped with large concentrations of …

The surface structure of P and B codoped colloidal Si-NCs are studied by
photoluminescence (PL) in hydrofluoric acid (HF) solution and X-ray photoelectron …

First-principles study of boron (B)-doped silicon nanocrystals (Si NCs) at 0 K in the
framework of density functional theory has been carried out. It is found that B prefers residing …
