Download or read book Supercritical Fluid Synthesis of Dilute Magnetic Semiconductor DMS and Hybrid Germanium Nanowire Structures written by Machteld Ingeborg Van der Meulen and published by . This book was released on 2009 with total page 199 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spintronics is an exciting new research field and has attracted a lot of attention since the discovery of the Giant Magneto Resistance (GMR) effect in 1988. Now research is facing the challenges of developing a second generation of spintronic devices, in which magnetic materials are integrated with semiconductor devices. Two types of material systems are momentarily investigated for second generation spintronic devices: (i) dilute magnetic semiconductors (DMSs) and (ii) magnetic/semiconductor hybrid spintronic devices. Germanium is of particular interest to form the fundamental basis of both spintronic material systems. The work in this thesis therefore describes the possibilities of exploiting a supercritical fluid (SCF) technique for synthesising Ge-based DMS nanowires and hybrid Ge nanowire structures. In Chapter 3 the SCF synthesis and structural properties of single crystalline Mn-doped Ge nanowires, with a doping concentration of between 0.5-1.0 atomic %, is described. The nanowires produced displayed ferromagnetism above 300 K and a superior performance with respect to the hole mobility of around 340 cm2/Vs, demonstrating the potential of using these nanowires as building blocks for electronic devices. In Chapter 4, the Mn doping process of Ge nanowires via supercritical fluid deposition (SCFD) methods is reported. Depending on the reaction conditions, Ge1-xMnx nanowires with different structural and magnetic properties were synthesised. Single crystalline nanowires with doping concentrations as low as 0.5-1.0 atomic % displayed long-range ferromagnetic ordering at room temperature, whilst polycrystalline nanowires, with a Mn20Ge80 leader, showed short-range ferromagnetic ordering at room temperature. In Chapter 5 the SCF synthesis of hybrid germanium nanowire structures is detailed, such as Co/Ge and Mn/Ge core/shell nanocables. Co/Ge nanocables showed clear ferromagnetic ordering at room temperature. Further a nanoparticulate CoxMnyGez alloy synthesised via SCFD exhibits strong ferromagnetic behaviour at room temperature, unlike CoxMnyGez thin films.

Available in PDF, EPUB and Kindle. Book excerpt: One dimensional electronic materials are expected to be key components owing to their potential applications in nanoscale electronics, optics, energy storage, and biology. Besides, compound semiconductors have been greatly developed as epitaxial growth crystal materials. Molecular beam and metalorganic vapor phase epitaxy approaches are representative techniques achieving 0D–2D quantum well, wire, and dot semiconductor III-V heterostructures with precise structural accuracy with atomic resolution. Based on the background of those epitaxial techniques, high-quality, single-crystalline III-V heterostructures have been achieved. III-V Nanowires have been proposed for the next generation of nanoscale optical and electrical devices such as nanowire light emitting diodes, lasers, photovoltaics, and transistors. Key issues for the realization of those devices involve the superior mobility and optical properties of III-V materials (i.e., nitride-, phosphide-, and arsenide-related heterostructure systems). Further, the developed epitaxial growth technique enables electronic carrier control through the formation of quantum structures and precise doping, which can be introduced into the nanowire system. The growth can extend the functions of the material systems through the introduction of elements with large miscibility gap, or, alternatively, by the formation of hybrid heterostructures between semiconductors and another material systems. This book reviews recent progresses of such novel III-V semiconductor nanowires, covering a wide range of aspects from the epitaxial growth to the device applications. Prospects of such advanced 1D structures for nanoscience and nanotechnology are also discussed.

Download or read book Fundamental Properties of Semiconductor Nanowires written by Naoki Fukata and published by Springer Nature. This book was released on 2020-11-16 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers virtually all aspects of semiconductor nanowires, from growth to related applications, in detail. First, it addresses nanowires’ growth mechanism, one of the most important topics at the forefront of nanowire research. The focus then shifts to surface functionalization: nanowires have a high surface-to-volume ratio and thus are well-suited to surface modification, which effectively functionalizes them. The book also discusses the latest advances in the study of impurity doping, a crucial process in nanowires. In addition, considerable attention is paid to characterization techniques such as nanoscale and in situ methods, which are indispensable for understanding the novel properties of nanowires. Theoretical calculations are also essential to understanding nanowires’ characteristics, particularly those that derive directly from their special nature as one-dimensional nanoscale structures. In closing, the book considers future applications of nanowire structures in devices such as FETs and lasers.

Available in PDF, EPUB and Kindle. Book excerpt: "Semiconductor nanowires, known for their high quality, large surface-to-volume ratio and coaxial quantum confinement, are a promising material for the next generation nano-electronics and nano-photonics devices. Intensive research on this material has been done over the past decade. In particular, the single nanowire electrical device, which can be fabricated using cleanroom technology and is compatible with the well-developed integrated-circuit processing technique, has significant practical applications. In this work, the complete process of fabricating a single nanowire device, from mask design to pre-patterned chip making, from nanowire transfer to nanowire device fabrication, from substrate preparation and cleaning to dicing, from spin-coating and exposure to developing, from metal deposition and lift-off to packaging, was carefully investigated. In addition, basic measurements and preliminary results such as resistance - temperature (R-T) behavior, resistance - magnetic field (R-B) behavior and current - voltage (I-V) curve, are shown. This thesis thus provides detailed information about compatibility of single semiconductor nanowires with the standard integrated-circuit technique and can serve as a manual for single nanowire electrical device fabrication." --

Available in PDF, EPUB and Kindle. Book excerpt: First-principles calculations were performed of a variety of materials systems of potential interest in spintronics. A comprehensive study was made of transitional metal doping in SiC and their magnetic properties. The trends in magnetic properties and in the preference for rocksalt versus zincblende structure were studied for the entire series of transition metal nitrides. The LSDA+U method was implemented in the FP-LMTO approach and applied to rare-earth nitrides and related compounds. A study was made of half-metallicity in zincblende transition metal compounds. A study was made of Mn doping of ScN. It was found to be a potentially interesting dilute magnetic semiconductor system. Exchange interactions in this system were calculated using a linear response approach and cluster variation method calculations indicate a Tc above room temperature should be feasible in this material. Calculations of the optical spectra of antifeorromagnetic MnN were compared with experimental data.
