Based on ab initio density functional calculations of Si nanocrystals (NCs) in a SiO 2 matrix
we study the impact of NC size and separation on electronic properties and present …

This work presents the benefits of the superlattice approach to control light emission
properties of materials with Si nanoclusters and rare‐earth ions. The undoped and Nd3+ …

The electron transport mechanisms through nanocomposite SiO 2 (Si) films containing Si
nanoclusters into dielectric SiO 2 matrix have been investigated. SiO 2 (Si) films were …

A multilayered thin film of SiO/Si has been irradiated by CO2 laser in a dot by dot scanning
mode, followed by furnace thermal annealing at 1100° C to form Si nanocrystals (Si-NCs) …

The electroluminescence (EL) and photoluminescence of Si nanocrystals (Si-nc) from
multilayered samples of Si/SiO are investigated. Si-nc are formed within Si and SiO layers …

The basic motivation of this thesis is to explore a path beyond the 29% fundamental
efficiency limit [1] of crystalline silicon (c-Si) through a reduction of the spectral losses of …

We report on electrical transport and quantum confinement in thermally annealed Si/SiOx
multiple quantum well (QW) stacks. Results are correlated with the morphology of the stacks …

We present a methodology for applying silicon pho-nonic crystals (Si PnCs) to photovoltaics
(PV). One-dimensional PnCs made from ultrathin Si, indium tin oxide, and graphene are …

The properties of Al2O3/Si/Al2O3 multiple quantum wells (MQWs) structures have been
investigated to find a possible application in optoelectronic devices. The structures were …

Si-based nano-structures are of a large interest of the photovoltaic community due to an
appealing combination of attributes and large sensitivity of the band gap energy on the …
