Abstract
Thin films of Ba0.8Sr0.2TiO3 were obtained by high-frequency sputtering on (100)p-Si substrates. Results of studies of frequency and temperature dependences of real and imaginary parts of dielectric permittivity of Ba0.8Sr0.2TiO3 ferroelectric film on alternating electric current are presented. It has been found that the polarization process has an activation character, the real and imaginary parts of the dielectric permeability decrease with increasing frequency, and the decrease rate is much higher at relatively low frequencies than at high frequencies. The relaxation time has been calculated and this crystal has been found to have an electron polarization mechanism due to thermal motion.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
