Nanostructured Semiconductors focuses on the development of semiconductor nanocrystals, their technologies and applications, including energy harvesting, solar cells, solid oxide fuel cells, and chemical sensors. Semiconductor oxides are used in electronics, optics, catalysts, sensors, and other functional devices. In their 2D form, the reduction in size confers exceptional properties, useful for creating faster electronics and more efficient catalysts. Since the first edition of the book, there has been significant progress in the development of new functional nanomaterials with unique and sometimes unpredictable quantum-confined properties within the class what it called two-dimensional (2D) semiconductors. These nanocrystals represent extremely thin nano-structures with thickness of just few nano-meters. Since that time, not only were 2D semiconductor oxides further developed, more importantly, 2D metal dichalcogenides, such as MoS2, MoSe2, WS2, WSe2 and others also progressed significantly in their development demonstrating their superior properties compared to their bulk and microstructural counterparts. The book has been expanded to include these advancements. The book begins with the structure and properties of semiconductor nanocrystals (chapter 1), addresses electronic device applications (chapter 2), discusses 2-Dimensional oxides and dichalcogenide semiconductors (chapters 3 through 5), and ends with energy, environment, and bio applications (chapters 6 through 8). Focuses on the development of semiconductor nanocrystals and their technologies and applications, including energy harvesting, solar cells, solid oxide fuel cells and chemical sensors Include other 2D materials, such as dichalcogenides to present a comprehensive resource on the latest advancements in nanostructured semiconductors Reviews the fundamental physics of conductivity and electron arrangement before proceeding to practical applications Contains a unique chapter dedicated to the new atomic layer deposition (ALD) technique which has the ability to develop 2D nanostructures with great precision

The book is devoted to nanostructures and nanostructured materials containing both amorphous and crystalline phases with a particular focus on their thermal properties. It is the first time that theoreticians and experimentalists from different domains gathered to treat this subject. It contains two distinct parts; the first combines theory and simulations methods with specific examples, while the second part discusses methods to fabricate nanomaterials with crystalline and amorphous phases and experimental techniques to measure the thermal conductivity of such materials. Physical insights are given in the first part of the book, related with the existing theoretical models and the state of art simulations methods (molecular dynamics, ab-initio simulations, kinetic theory of gases). In the second part, engineering advances in the nanofabrication of crystalline/amorphous heterostructures (heavy ion irradiation, electrochemical etching, aging/recrystallization, ball milling, PVD, laser crystallization and magnetron sputtering) and adequate experimental measurement methods are analyzed (Scanning Thermal Microscopy, Raman, thermal wave methods and x-rays neutrons spectroscopy).

This book, Nanostructured Semiconductors in Porous Alumina Matrices: Modeling, Synthesis, and Properties, explores new developments in the modeling, synthesis, and properties of functional semiconductor nanostructures in porous anodic alumina matrices. The book focuses on luminescent nanoparticles in organic and inorganic dielectric matrixes, specifically in porous alumina films, as these are most relevant due to their capacity for particle division and ability to provide environmental protection. With a particular emphasis on experimental and theoretical studies of the synthesis processes, the book informs readers about these nanostructures through rigorous investigation of their properties. The book, which is divided into ten chapters, begins with a discussion of the existing literature on nanostructural electroluminescent light sources (ELS). This overview establishes a foundation for the remaining nine chapters, which explore in depth many facets of nanostructured materials: their composition, processes they undergo, how they may be implemented, etc. Within these chapters, experimental studies and results are incorporated, in addition to detailed descriptions of simulations that highlight different uses of these materials.

The use of light to channel signals around electronic chips could solve several current problems in microelectronic evolution including: power dissipation, interconnect bottlenecks, input/output from/to optical communication channels, poor signal bandwidth, etc. It is unfortunate that silicon is not a good photonic material: it has a poor light-emission efficiency and exhibits a negligible electro-optical effect. Silicon photonics is a field having the objective of improving the physical properties of silicon; thus turning it into a photonic material and permitting the full convergence of electronics and photonics.

Due to their unique optical, thermal, catalytic, magnetic and electronic properties, nano-sized semiconductors have a huge potential in a great number of technological applications, ranging from photovoltaics and photocatalysis to biosensors and medicine. In the last couple of decades, the synthesis and characterization of these materials has been of key interest not only to materials scientists but also to researchers working in the field of physics, chemistry, molecular biology and medicine. The main focus of the present book is the characterization of a number of nano-semiconducting materials, using such techniques as powder X-ray diffraction, UV-visible spectrophotometry, Raman spectrometry, scanning electron microscopy, transmission electron microscopy and vibrating sample magnetometry. The materials studied include ZnS, TiO2, NiO, Ga doped ZnO, Mn doped SnO2, Mn doped CeO2 and Mn doped ZrO2. Of special interest has been the analysis of the electron density distribution within the nano samples. The results give deep insights into the atomic structures on which these crystals are based and on the binding characteristics between the atoms and the ways in which these characteristics can be changed. As the decisive properties of these materials depend upon the electron density distributions and their variations due to sample preparation specifics, temperature and the presence of doping elements, these results give important hints on the direction in which further research should be directed.
