ISSN: 1572-817XSource: Springer Online Journal Archives 1860-2000Topics: Electrical Engineering, Measurement and Control TechnologyPhysicsNotes: Abstract The temperature dependence of two-beam coupling and dark decay in photorefractive BaTiO3 is reported. We show that the competition between deep and shallow traps depends on temperature and writing intensity, and influences two-beam coupling and dark decay. The dynamics of dark decay, characterized by a fast decay of partial erasure and a subsequent slow decay, is influenced by the presence of deep and shallow traps. Partial erasure, due to thermal excitation of charges from the shallow traps, decreases with temperature and increases with writing intensity. The time constant of the slow decay, due to thermal excitation of charges from the deep traps, depends strongly on temperature, but not on the writing intensity. At room temperature, the existence of deep and shallow trap leads to intensity-dependent photorefractive gains. As temperature increases, the influence from the shallow trap decreases, and the photorefractive gain becomes independent of the intensity. However, at much higher temperatures (∼100°C), the photorefractive gain resumes its dependence on intensity due to an increase in dark conductivity at elevated temperature.Type of Medium: Electronic ResourceURL: -

Published 1991Staff ViewISSN: 0377-0486Keywords: Chemistry ; Analytical Chemistry and SpectroscopySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyPhysicsNotes: Raman spectra of a series of MgO-doped congruent LiNbO3 crystals were obtained with MgO concentrations up to 30 mol.%. Single crystals were successfully grown and no precipitates were discovered. The intensity, frequency and line width of the Raman phonons were studied as a function of doping percentage. An abrupt change was observed near the composition of 7.5 mol.% of MgO-doped LiNbO3 crystal. From the spectral changes it is proposed that Mg2+ replaces the mis-sited Nb5+ cation at Li sites first. When these mis-sited Nb5+ cations have been completely replaced, the Mg2+ cation then replaces the Li+ cation and creates vacancies at Li+ sites.Additional Material: 6 Ill.Type of Medium: Electronic ResourceURL:
