Theoretical Modeling of Inorganic Nanostructures


Book Description

This book deals with the theoretical and computational simulation of monoperiodic nanostructures for different classes of inorganic substances. These simulations are related to their synthesis and experimental studies. A theoretical formalism is developed to describe 1D nanostructures with symmetric shapes and morphologies. Three types of models are considered for this aim: (i) nanotubes (rolled from 2D nanolayers and described within the formalism of line symmetry groups); (ii) nanoribbons (obtained from 2D nanolayers by their cutting along the chosen direction of translation); (iii) nanowires (obtained from 3D lattice by its sectioning along the crystalline planes parallel to the chosen direction of translation). Quantum chemistry ab-initio methods applied for LCAO calculations on electronic and vibrational properties of 1D nanostructures are thoroughly described. Understanding of theoretical aspects presented here enlarges the possibilities for synthesis of monoperiodic nanostructures with predictable morphology and better interpretation of their properties.




Theoretical Modeling of Inorganic Nanostructures


Book Description

This book summarizes the state of the art in the theoretical modeling of inorganic nanostructures. Extending the first edition, published in 2015, it presents applications to new nanostructured materials and theoretical explanations of recently discovered optical and thermodynamic properties of known nanomaterials. It discusses the developments in theoretical modeling of nanostructures, describing fundamental approaches such as symmetry analysis and applied calculation methods. The book also examines the theoretical aspects of many thermodynamic and the optical properties of nanostructures. The new edition includes additional descriptions of the theoretical modeling of nanostructures in novel materials such as the V2O5 binary oxide, ZnS, CdS, MoSSe and SnS2.




Self-Assembled Organic-Inorganic Nanostructures


Book Description

The current state and perspectives in natural and life sciences are strongly linked to the development of novel complex organic-inorganic materials at various levels of organization, including semiconductor quantum dots (QDs) and QD-based nanostructures with unique optical and physico-chemical properties. This book provides a comprehensive description of the morphology and main physico-chemical properties of self-assembled inorganic-dye nanostructures as well as some applications in the field of nanotechnology. It crosses disciplines to examine essential nanoassembly principles of QD interaction with organic molecules, excited state dynamics in nanoobjects, theoretical models, and methodologies. Based on ensemble and single-nanoobject detection, the book quantitatively shows (for the first time on a series of nanoassemblies) that surface-mediated processes (formation of trap states) dictate the probability of several of the most interesting and potentially useful photophysical phenomena (FRET- or non-FRET-induced quenching of QD photoluminescence) observed for colloidal QDs and QD–dye nanoassemblies. Further, nanostructures can be generated by nanolithography and thereafter selectively decorated with dye molecules. A similar approach applies to natural nanosized surface heterogeneities.

Computational Materials Discovery


Book Description

New technologies are made possible by new materials, and until recently new materials could only be discovered experimentally. Recent advances in solving the crystal structure prediction problem means that the computational design of materials is now a reality. Computational Materials Discovery provides a comprehensive review of this field covering different computational methodologies as well as specific applications of materials design. The book starts by illustrating how and why first-principle calculations have gained importance in the process of materials discovery. The book is then split into three sections, the first exploring different approaches and ideas including crystal structure prediction from evolutionary approaches, data mining methods and applications of machine learning. Section two then looks at examples of designing specific functional materials with special technological relevance for example photovoltaic materials, superconducting materials, topological insulators and thermoelectric materials. The final section considers recent developments in creating low-dimensional materials. With contributions from pioneers and leaders in the field, this unique and timely book provides a convenient entry point for graduate students, researchers and industrial scientists on both the methodologies and applications of the computational design of materials.
