Описание: 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.
Описание: Nanocrystals and Their Mesoscopic Organization is an up-to-date monograph on an important aspect of nanoscience and technology. It opens with an elegant introduction including a brief historical account. Emphasis is then given to diverse synthetic methods, both chemical and physical, in addition to modern hybrid methods. The orientation shifts gradually to properties of nanocrystals that evolve with size; detailed discussions are to be found on mesoscalar assemblies in different dimensions, special cases of core-shell and magic nuclearity nanocrystals. The authors also address applications of nanocrystals, carefully separating out potential applications and those that have already emerged, and cite around 900 references from the literature, most from the last decade. Tables providing information at a glance and schematic diagrams at relevant places, make the monograph appealing to read. Occasionally, the reader is reminded of the contributions of celebrated past masters such as Michael Faraday. In summary, the monograph serves as a general introduction as well as a handy reference for the entire community of researchers and practitioners.
Описание: Describes synthesis, characterization, and applications of nanoparticles.

Описание: In seventeen chapters contributed by experts in the field, this book explores the varied physical properties of ZnO nanocrystals, helping researchers envisage device applications of ZnO and allied materials in thin film, heterostructure nanostructure forms.
Описание: Semiconductor nanostructures are ideal systems to tailor the physical properties via quantum effects, utilizing special growth techniques, self-assembling, wet chemical processes or lithographic tools in combination with tuneable external electric and magnetic fields. Such systems are called "Quantum Materials".
Описание: Since the size, shape, and microstructure of nanocrystalline materials strongly impact physical and chemical properties, the development of new synthetic routes to nanocrystals with controlled composition and morphology is a key objective of the nanomaterials community. This objective is dependent on control of the nucleation and growth mechanisms that occur during the synthetic process, which in turn requires a fundamental understanding of both classical nucleation and growth and non-classical growth processes in nanostructured materials. Recently, a novel growth process called Oriented Attachment (OA) was identified which appears to be a fundamental mechanism during the development of nanoscale materials. OA is a special case of aggregation that provides an important route by which nanocrystals grow, defects are formed, and unique—often symmetry-defying—crystal morphologies can be produced. This growth mechanism involves reversible self-assembly of primary nanocrystals followed by reorientation of the assembled nanoparticles to achieve structural accord at the particle-particle interface, the removal of adsorbates and solvent molecules, and, finally, the irreversible formation of chemical bonds to produce new single crystals, twins, and intergrowths. Crystallization and Growth of Colloidal Nanocrystals provides a current understanding of the mechanisms related to nucleation and growth for use in controlling nanocrystal morphology and physical-chemical properties, and is essential reading for any chemist or materials scientist with an interest in using nanocrystals as building blocks for larger structures. This book provides a compendium for the expert reader as well as an excellent introduction for advanced undergraduate and graduate students seeking a gateway into this dynamic area of research.

Описание: Melt quenching—the method of quenching from the liquid state—provides new opportunities for producing advanced materials with a unique combination of properties. In the process of melt quenching, attainment of critical cooling rates can produce specific structural states of the material. Nanocrystalline materials produced by melt quenching are classified as nanomaterials not only by their nanoscale structural elements but also by the effects these elements have on the properties of the material.The result of 30 years of research, Melt-Quenched Nanocrystals presents a detailed and systematic analysis of the nanostructured state formed in the process of melt quenching and subsequent thermal and deformation effects. It covers the metallurgical and mechanical properties of nanomaterials, focusing particularly on properties derived from nanocrystals and their agglomeration. The text introduces four different types of nanocrystals that can be produced by melt quenching, each having different structures and properties: Type I nanocrystals formed when crystallization takes place completely during melt quenching Type II nanocrystals formed when melt quenching is accompanied by amorphous state formation along with partial or complete crystallization Type III nanocrystals formed when melt quenching results in the formation of the amorphous state, and nanocrystals can be produced as a result of the subsequent thermal effect Type IV nanocrystals formed when melt quenching leads to the formation of the amorphous state, and nanocrystals can be produced as a result of the subsequent deformation effect The possible uses for these materials are extensive, with applications from coatings to biological compatibility. The final section of the book presents a discussion of existing and future applications of nanocrystals produced by different melt-quenching methods.
