GaN three-dimensional columnar core-shell LEDs are considered to be one of the promising candidates for prospective solid state lighting. In comparison to conventional planar layer LEDs, columnar core-shell LEDs have many advantages. For instance, in a columnar GaN coreshell LED structure the InGaN/GaN MQW wraps around the column, therefore the light emitting area can be enormously increased. This is the main driving force behind the intense investigation of nanowire and micro-columnar LEDs. In addition, because of the increased area of the MQW, the internal quantum efficiency may be improved by a reduction of the local carrier density, mitigating the efficiency droop. Besides, due to the reduced influence of thermal and lattice mismatch between the substrate and columns, dislocation-free GaN column arrays can be achieved on large area substrates. The main contribution of the present work is the controlled growth of GaN columns and core-shell LEDs by metal-organic vapor-phase expitaxy. The growth conditions which lead to vertical growth of N-polar and Ga-polar GaN columns are systematically investigated. The causes of the vertical growth are explained by surface processes under appropriate conditions for both polarities. Quantitative discussions of growth kinetics of GaN columns are an important feature in this work. The difficulties and the strategies of the MQW and p-GaN shell growth on high aspect ratio GaN columns are presented in detail.

Systematically discusses the growth method, material properties, and applications for key semiconductor materials MOVPE is a chemical vapor deposition technique that produces single or polycrystalline thin films. As one of the key epitaxial growth technologies, it produces layers that form the basis of many optoelectronic components including mobile phone components (GaAs), semiconductor lasers and LEDs (III-Vs, nitrides), optical communications (oxides), infrared detectors, photovoltaics (II-IV materials), etc. Featuring contributions by an international group of academics and industrialists, this book looks at the fundamentals of MOVPE and the key areas of equipment/safety, precursor chemicals, and growth monitoring. It covers the most important materials from III-V and II-VI compounds to quantum dots and nanowires, including sulfides and selenides and oxides/ceramics. Sections in every chapter of Metalorganic Vapor Phase Epitaxy (MOVPE): Growth, Materials Properties and Applications cover the growth of the particular materials system, the properties of the resultant material, and its applications. The book offers information on arsenides, phosphides, and antimonides; nitrides; lattice-mismatched growth; CdTe, MCT (mercury cadmium telluride); ZnO and related materials; equipment and safety; and more. It also offers a chapter that looks at the future of the technique. Covers, in order, the growth method, material properties, and applications for each material Includes chapters on the fundamentals of MOVPE and the key areas of equipment/safety, precursor chemicals, and growth monitoring Looks at important materials such as III-V and II-VI compounds, quantum dots, and nanowires Provides topical and wide-ranging coverage from well-known authors in the field Part of the Materials for Electronic and Optoelectronic Applications series Metalorganic Vapor Phase Epitaxy (MOVPE): Growth, Materials Properties and Applications is an excellent book for graduate students, researchers in academia and industry, as well as specialist courses at undergraduate/postgraduate level in the area of epitaxial growth (MOVPE/ MOCVD/ MBE).

The aim of the contributions in this volume is to give a current overview on the basic properties and applications of semiconductor and nonlinear optical materials for optoelectronics and integrated optics. They provide a cross-linkage between different materials (III-V, II-VI, Si-Ge, glasses, etc.), various sample dimensions (from bulk crystals to quantum dots), and a range of techniques for growth (LPE to MOMBE) and for processing (from surface passivation to ion beams). Major growth techniques and materials are discussed, including the sophisticated technologies required to exploit the exciting properties of low dimensional semiconductors. These proceedings will prove an invaluable guide to the current state of optoelectronic and nonlinear optical materials development, as well as indicating trends and also future markets for optoelectronic devices.

The chemical aspects of materials processing used for electronic applications, e.g. Si, III-V compounds, superconductors, metallization materials, are covered in this volume. Significant recent advances have occurred in the development of new volatile precursors for the fabrication of III-V semiconductor and metal [Cu, W] films by OMCVD. Some fundamentally new and wide-ranging applications have been introduced in recent times. Experimental and modeling studies regarding deposition kinetics, operating conditions and transport as well as properties of films produced by PVD, CVD and PECVD are discussed. The thirty papers in this volume report on many other significant topics also. Research workers involved in these aspects of materials technology may find here some new perspectives with which to augment their projects.
