Book Description
We report on the effect of the deposition temperature of SrTiO3 on the dielectric properties of SrTiO3/YBa2Cu3O(7-delta)/LaAlO3 thin film multilayer structures. In these structures, the YBa2Cu3O(7-delta) a (YBCO) films were deposited at 800 C by laser ablation, followed by the in-situ deposition of the SrTiO3 (STO) layer at one of the following temperatures: 750 C, 650 C, 550 C, 450 C, 350 C, and 250 C. Gold (Au) films were deposited and patterned on top of the STO layer to form planar Au/STO/YBCO capacitor structures. The electrical response was studied by measuring the dielectric constant (epsilon (sub r)) and loss tangent (tan delta) of the ferroelectric film from 300-40 K, at 1.0 MHz, and at electric fields up to 100 kV/cm. Our results show 750 C to be a deposition temperature which allows for large variations of epsilon(sub r) with limited enhancement of tan delta, while lower deposition temperatures cause a reduction of the induced change in epsilon(sub r) and an increase in tan delta with applied field.

Structure and Bonding in Crystalline Materials
Author: Gregory S. Rohrer
Publisher: Cambridge University Press
ISBN: 9780521663793
Category : Science
Languages : en
Pages : 554
Book Description
One of the motivating questions in materials research today is, how can elements be combined to produce a solid with specified properties? This book is intended to acquaint the reader with established principles of crystallography and cohesive forces that are needed to address the fundamental relationship between the composition, structure and bonding. Starting with an introduction to periodic trends, the book discusses crystal structures and the various primary and secondary bonding types, and finishes by describing a number of models for predicting phase stability and structure. Containing a large number of worked examples, exercises, and detailed descriptions of numerous crystal structures, this book is primarily intended as an advanced undergraduate or graduate level textbook for students of materials science. It will also be useful to scientists and engineers who work with solid materials.
