I.E. Barry, “Microstructuring of lithium niobate,” PhD research thesis, Optoelectronics Research Centre, Faculty of Science, University of Southampton (2000). Fleming, “Optically matched trilevel resist process for nanostructure fabrication,” J. Lithiumniobat kann zum Beispiel durch Festkörper- oder Schmelzenreaktion von Lithiumcarbonat mit Niob(V)-oxid gewonnen werden. Als Koordinationspolyeder ergibt sich für Lithium ein stark verzerrtes Antikuboktaeder. The z- face is flat showing the 3D feature of the obtained crystal structures. A.C. Busacca, V. Apostolopoulos, R.W. Carrier density and conductivity of the samples were increased via heating LN, which inhibited coulomb explosion to obtain a uniform periodic surface structure. The measurement was performed along the x main axis of the crystal. M. Osgood, ed. (Springer, 2010), Chap. Welling, and A. Tünnermann, “Electrode geometries for periodic poling of ferroelectric materials,” Opt. We show that high etch-rate applied to such structures allows to obtain pyramidal-like submicron relief structures which in principle could find application for waveguide construction in photonic bandgap devices. We report on the first realization of photonic crystal structures in 600-nm thick ion-sliced, single-crystalline lithium niobate thin films bonded on a lithium niobate substrate using adhesive polymer benzocyclobutene (BCB). Vac. Sci. Technol. B 13, metformin drug 1973–1978 (1995). A. J. Eccles, J. A. van den Berg, A. Lithiumniobat zeigt eine Anzahl physikalischer Effekte: die stöchiometrische Zusammensetzung (LiNbO3) ist unterhalb der Curie-Temperatur Tc von 1213 °C (1486 K) [5] ferroelektrisch und dadurch optisch nichtlinear, elektrooptisch, photorefraktiv, elastooptisch, seroquel 100 piezoelektrisch und pyroelektrisch. Fluence, 7.0  kJ/m2; N2 pressure, 500 Torr; scanning speed, 2 mm/s. Russell, J.R.M. Barr, and D.C. Brown, and J. C. Vickerman, “Evidence of a charge induced contribution to the sputtering yield of insulating and semiconducting materials,” Appl. The periodic surface structures cover an area of 8  mm×8  mm and have an average spacing of 174±5  nm. Some methods for estimating the concentration of vacancies in crystals and procedures for decreasing their number are considered by the example of LiNbO3, SrTiO3, YAlO3, and PbWO4 crystals. T.-H.

Campbell, “A general continuum approach to describe fast electronic transport in pulsed laser irradiated materials: the problem of Coulomb explosion,” Appl. S. Diziain, J. Amet, F.I. Baida, and M.-P.

Istituto Nazionale di Ottica Applicata, Largo E. R. S. Weis and T. K. Gaylord, “Lithium niobate: summary of physical properties and crystal structure,” Appl. All samples were fabricated with the fluence of 7.0  kJ/m2 at 2 mm/s scanning speed, 500 Torr N2 pressure, and the temperatures of 28°C, 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, and 800°C, respectively. L. Razzari, P. Minzioni, and I. Phys. Lett. 65, 1850–1852 (1994). Guyot, J. -M. Merolla, M. Collet, F. This is in good agreement with numerical simulations based on the three-dimensional plane wave expansion (PWE) and the finite-difference time-domain (FDTD) method. V. Pruneri, J. Webjörn, P.St.J. Structural imperfections (dislocations, pores, and twins) in CdWO4 single crystals are investigated by microstructural analysis and x-ray diffraction. K. Wong, ed. (Inspec, 2002), Chap. Fig. 15. Movie (1.56 MB) which shows the pyramidal-like morphology of the structures revealed on the 3D domain patterned sample A by 45 minutes etching process at 100°C. Proc. 1464, 428–441 (2012). Die ferroelektrische Curie-Temperatur ist abhängig von der Zusammensetzung, so beträgt sie für die kongruente Zusammensetzung (hergestellt aus 48,45 % Li2O, 51,55 % Nb2O5) 1143 °C (1416 K).[5] Oberhalb der Curie-Temperatur verliert das Material die ferroelektrischen Eigenschaften und geht in die paraelektrische Phase (Raumgruppe R3c (Nr.
