This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to novel properties which arise when a material is reduced to the nanoscale, colloidal semiconductor nanocrystals (NCs) are of interest for use in technologies ranging from solar energy conversion to quantum computing. The benefits of NCs over their bulk counterparts include high surface-to-volume ratio, potential quantum confinement, and increased heterojunction lattice mismatch tolerance. Utilizing these potential benefits requires both identification of desirable materials and development of size, morphology, and material specific synthetic strategies. This work looks at two NC materials systems, one for solar energy conversion and the other for spintronics applications. The first materials system presented is lead selenide NC - hematite nanowire (NW) epitaxial heterostructures for solar energy conversion. Herein we combine tradition colloidal NCs and vapor-phase NW methods to synthesizing epitaxial quantum dot-nanowire (QD-NW) heterostructures consisting of high-quality, epitaxially-connected, colloidal PbSe QDs on furnace-grown hematite (ÎI-Fe2O3) NWs, synthesized through direct heterogeneous nucleation of the PbSe. NC diameter, diameter distribution, and NC surface coverage were shown to be tuned via the reaction temperature and the length of time of the surface dehydration. The second materials system presented is europium sulfide (EuS) and gadolinium doped EuS (Euitalic1-xitalicGditalicxS) NCs for spintronics applications. As a ferromagnetic semiconductor and ideal Heisenberg ferromagnetic, EuS is interesting for applications which utilize both electron charge and spin such as spintronics and magneto-optics. EuS NCs were synthesized through high temperature decomposition of a dithiocarbamate single source precursor (SSP). Ferromagnetic hysteresis and Curie temperature (TCc) were determined for ensembles of NCs by vibrating sample magnetometry (VSM). The element and oxidation state specific magnetic origin was determined to be Eu2+ using X-ray magnetic circular dichroism. The low TsubC of EuS limits utility and this temperature was enhanced by doping the EuS nanocrystals with gadolinium (III) as has been reported for bulk samples. Homogeneously doped Euitalic1-xsubitalicGdsubitalicxS NCs were synthesized through the development and subsequent simultaneous decomposition of novel Eu and Gd SSPs. The maximum TsubC achieved was 29.4 K for NCs containing 5.3 % Gd.

Book excerpt: This book is intended to provide knowledge for students and learners in the field of nanoscale science and nanotechnology. Nanotechnology is design, fabrication and application of nanostructures or nanomaterials, and the fundamental understanding of the relationships between physical properties or phenomena and material dimensions. Nanotechnology deals with materials or structures in nanometer scales, typically ranging from subnanometers to several hundred nanometers. Nanotechnology is a new field or a new scientific domain. Similar to quantum mechanics, on nanometer scale, materials or structures may possess new physical properties or exhibit new physical phenomena. Nanotechnology has an extremely broad range of potential applications from nanoscale electronics and optics and therefore it requires formation of and contribution from multidisciplinary teams of physicists, chemists, materials scientists and engineers. The aim of this book “Growth and Characterization of Semiconductor Nanostructure for Device Applications” is to summarize the fundamentals and established techniques of synthesis, fabrication, characterization and applications of nanomaterials and nanostructures so as to provide readers a systematic and coherent picture about synthesis, fabrication and characterization of nanomaterials.
