This book covers the crucial aspects of theoretical and experimental approaches for Si-based spintronic materials. The theory parts emphasize on two first-principles methods - the GW method to improve the insulating gaps of the half metals which are a class of materials ideal for spintronic applications, and the linear response theory to calculate electric and magnetic susceptibilities. Three growth methods for doping transition metal elements in alloy and layered forms in Si will be focused on. Also three methods for characterization will be presented emphasizing on how to interpret experimental results. Finally, recent progress made in the Si-based spintronic materials will be discussed. This book is intended for researchers and graduate students who are interested in designing and growing new spintronic materials, in particular, silicon-based.

Aims to rebut the common belief that grave environmental consequences are associated with the issues of global warming and nuclear hazards. This book describes the revolution in climatology through scientific discoveries that solve the longstanding mystery of the ice ages and explain the enigma of the missing greenhouse heat.

This volume provides a detailed treatment of half-metallic materials and their properties from both an experimental and theoretical point of view. It discusses the methods used to understand and predict the properties of half-metals and the gamut of other materials amenable to these techniques. It also offers an expansive bibliography to facilitate further and deeper research. This book provides the precise definitions of all key terminology used in the vast and varied literature. This is the first comprehensive monograph on the subject and will serve as a starting point for graduate students and senior researchers who wish to enter the field. This book will also be an invaluable reference to those already working in the area of half-metallic materials.
