Book excerpt: Even if the discovery of the photoluminescence of porous silicon dates to more than twenty years ago, the research on the optical properties of silicon is still a hot topic. The most recent experimental techniques have allowed the successful synthesis of silicon nanoparticles with narrow size distributions, and the realization of light-emitting silicon devices for technological and biomedical applications. From the theoretical point of view, the physics of silicon nanocrystals still deserves a huge interest. While the quantum confinement effect has been recognized as the main cause of the photoluminescence, many doubts remain on the way in which the phenomenon takes place in real nanocrystals. This book summarizes the result of a work lead by the author at the University of Naples. The density of states, the optical gap, the absorption spectra, the static dielectric constant, the recombination times, are all illustrated for several sets of silicon spheres and ellipsoids, upon changing their size and aspect ratio. The book also reviews previous research work, with special reference to the experimental and theoretical literature on silicon nanocrystals.

Available in PDF, EPUB and Kindle. Book excerpt: This unique collection of knowledge represents a comprehensive treatment of the fundamental and practical consequences of size reduction in silicon crystals. This clearly structured reference introduces readers to the optical, electrical and thermal properties of silicon nanocrystals that arise from their greatly reduced dimensions. It covers their synthesis and characterization from both chemical and physical viewpoints, including ion implantation, colloidal synthesis and vapor deposition methods. A major part of the text is devoted to applications in microelectronics as well as photonics and nanobiotechnology, making this of great interest to the high-tech industry.

Book excerpt: Zusammenfassung: AbstractThis dissertation is focused on the fundamental investigation of Si nanocrystals formed in annealed Si rich/stoichiometric dielectric multilayered structures. The films are prepared by size-controlled superlattices approach previously widely applied to SiOx/SiO2 superlattices. While a deep understanding of fundamental properties of Si nanocrystals in SiOx matrix has been already achieved, most of the results published on silicon nanocrystals in SiNx do not represent a clear understanding and sometimes even contradict to each other.Thereby, a starting point of the present research is a detailed study of Si nanocrystals embedded in Si nitride matrix. A careful development of plasma-enhanced chemical vapor deposition parameters allowed the deposition of optimized SiNx/Si3N4 superlattices of various SiNx thicknesses, which were further annealed in order to form Si nanocrystals of various sizes. Based on transmission electron microscopy and X-ray diffraction analysis, the formation of size-controlled Si nanocrystals of various sizes is confirmed. Despite photoluminescence spectra of these samples demonstrate the expected PL blue shift with the decrease of Si nanocrystal size, the shift is confirmed to be an optical artifact. The results presented here can explain a disagreement of the recent reports published on Si nanocrystals in SiNx matrix by other groups, as the photoluminescence peak shift is sometimes wrongly interpreted as nanocrystal size effect. Additionally, according to the concluded issues, novel hetero-combinations, which contain both silicon nitride and silicon oxide sublayers are proposed and realized. Although SiNx/SiO2 and SiOxNy/Si3N4 hetero-structures might show some benefits in optical and electrical properties compared to the standard SiOx/SiO2 and SiNx/Si3N4 superlattices, they have been only very barely studied previously. In the present work it is shown that high-temperature annealing leads to the destruction of SiNx/SiO2 hetero-superlattice, and Si nanocrystals of uncontrollable sizes irregularly distributed within the film are formed. At the same time SiOxNy/Si3N4 hetero-structure sustains high-temperature annealing and size-controlled Si nanocrystals demonstrate quantum luminescence

Book excerpt: Recent developments in the technology of silicon nanocrystals and silicon nanostructures, where quantum-size effects are important, are systematically described including examples of device applications. Due to the strong quantum confinement effect, the material properties are freed from the usual indirect- or direct-bandgap regime, and the optical, electrical, thermal, and chemical properties of these nanocrystalline and nanostructured semiconductors are drastically changed from those of bulk silicon. In addition to efficient visible luminescence, various other useful material functions are induced in nanocrystalline silicon and periodic silicon nanostructures. Some novel devices and applications, in fields such as photonics (electroluminescence diode, microcavity, and waveguide), electronics (single-electron device, spin transistor, nonvolatile memory, and ballistic electron emitter), acoustics, and biology, have been developed by the use of these quantum-induced functions in ways different from the conventional scaling principle for ULSI.
