Chapter
Ferroelectric Nanostructures
Ferroelectricity is known to be sensitive to strain, and therefore, salient effects of nanostructures on ferroelectric properties can be expected. We introduce recent first-principles calculations of ferroelec...

Chapter
Multiferroic Nanostructures
Multiferroics, two or more ferroic orders such as ferroelectricity and antiferromagnetism coexist and coupled with each other, is a tremendously fascinating topic in terms of scientific interests as well as po...

Chapter
Magnetism in Nanostructures
As magnetism is susceptible to structures and strains as well as crystal defects, extensive investigations by means of first-principles calculations have been devoted to this matter. We review a series of stud...

Chapter
Ferroic Nanometamaterials and Composites
Metamaterials, which possess artificially designed lattice-shaped internal structures, gain remarkably increasing attention owing to their unique, controllable, and often unprecedented properties. We review a ...

Ideal Strength in Low-Dimensional Nanostructures
The ideal strength is the theoretical strength of materials setting the limit of stress attained and is therefore an important fundamental quantity describing mechanical behavior of materials. While a substant...
