Keywords: | Dielectric response;Plasma flow;Raman scattering;Strontium titanate;Surface science;X-ray diffraction | Issue Date: | 30-Apr-2010 | Journal: | Journal of Alloys and Compounds | Abstract: | The frequency and temperature dependences of dielectric properties of SrTiO3:Sm were investigated over the frequency range from 80 kHz to 10 MHz and temperature range from 30 K to 300 K. The Raman spectroscopic investigations of SrTiO3:Sm were performed in a wide temperature (25 K to RT) and frequency range (30-150 cm-1). The T-behavior of the broad band has been studied in detail. Surface of SrTiO3:Sm single crystal was treated by quasistationary compression plasma flow produced by magnetoplasma compressor. To investigate the microstructure and morphology of treated samples SEM techniques were used both with XRD analysis. It was observed that quasi-ordered structures were formed on the surface about 1 μm in size. © 2010 Elsevier B.V. All rights reserved. |
