Materials Science and Technology Series: Synthetic Modulated Structures focuses on synthetic modulated structures, which is described as any periodically perturbed materials with a repetition greater than the basic unit cell dimension. The book is organized into three parts. Part I provides a perspective of developments and structural characterization of the semiconductor and metal area. The electronic properties in different configurations and structures, including compositional and doping modulation are covered in Part II. Part III begins with preparation methods, followed by a discussion on distinctive fields of interest in metals, transport and magnetic properties, superconductivity, and diffusion. This publication is a good source for students and researchers conducting work in the general area of modulated structures.
