The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

This is a new and greatly revised edition of Professor Chandrasekhar's classic book Liquid Crystals, first published in 1977. The subject of liquid crystals has grown into an exciting interdisciplinary research field with important practical applications. This book presents a systematic and self-contained treatment of the physics of the different types of thermotropic liquid crystals - the three classical types, nematic, cholesteric and smectic, and the newly discovered discotic type. Included is a description of the structures of these four main types and their polymorphic modifications, their thermodynamical, optical and mechanical properties and their behaviour under external fields. The basic principles underlying the major applications of liquid crystals in display technology and in thermography are also discussed. This book will be of great value to advanced students and researchers in condensed matter physics, chemical physics, materials science and technology with an interest in the physics, chemistry and applications of liquid crystals.

Liquid crystal technology is one of the most important developments in today's world. Materials can have their molecules realigned, using magnetic or electrical fields, and in the process acquire the properties of both solids and liquids. These new materials are also inexpensive, occupy small spaces, and use little energy. As a result, liquid crystal materials are increasingly used in everyday objects: notebook computer screens, flat screen TV's, stereo displays, 3-D computer chips, and displays on phones and digital watches. This book brings together the most important research from this field in the last 15 years, presenting a timely reference for professionals in chemistry and physics, and those leading institutions and businesses that work with cutting-edge technologies. The book covers both theory and practice, explaining the processes that govern liquid crystals and their scientific and technological applications. Extensive references to papers and reviews on critical aspects of this technology are included. An introductory chapter gives readers a general background, followed by chapters from leading experts on such topics as synthesis and new materials, theory and computation, phase structures and transitions, ferroelectrics and external field effects, interfaces and surfaces, liquid crystal polymers, addressing schemes, communication devices, optical linear phenomena in liquid crystals, and bistable displays. Anyone who works with liquid crystals will find this an indispensable reference.

The study of ferroelectricity is a branch of solid state physics which has shown rapid growth during the recent years. Ferroelectric materials exhibit unusual electric properties which make them useful in modern (opto)electronic technology, esp. display technology. Ferroelectric and antiferroelectric liquid crystals, including also various polymer forms, are the hottest research topic today in liquid crystals. The field is at the very beginning of industrial exploitation - a sensitive phase in which a good reference work is needed and will have a broad spectrum of readers both at universities and in industry.
