IL EST MONTRE QUE LE PHENOMENE DE SAUT, LE PLUS PROBABLE, EST CELUI CONTROLE PAR L'INTERACTION ELECTROSTATIQUE ENTRE LES ELECTRONS LOCALISES DANS LA BANDE INTERDITE. LES ANALYSES XPS EN FONCTION DU TEMPS DE DECAPAGE DES INTERFACES, COUCHE MINCE DE SELENIUM/COUCHE MINCE DE METAL (NICKEL, ALUMINIUM, TELLURE) ONT MONTRE QU'IL N'Y A AUCUNE FORMATION DE COMPOSES METAL-SELENIUM, LA SURFACE DU METAL ETANT PASSIVEE PAR LA FORMATION D'OXYDE.

Book Synopsis Flexoelectricity in Liquid Crystals by : Agnes Buka
Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
