Fabrication and Electrical Properties of Mn-Doped KNbO₃ Ceramics Synthesized from KHCO₃ as a Starting Material

Abstract

Silicon-on-insulator (SOI) is a strong candidate for application in future planar waveguide integration technology, whether or not luminescence is extracted from the silicon. We review recent research on photonic devices based on silicon-on-insulator. These devices exploit either photonic crystal or photonic wire concepts-or combinations of both. Aspects of the technologies used that are particularly critical for successful implementation of SOI-based photonics are addressed.Institute of Physics ⌽ DEUTSCHE PHYSIKALISCHE GESELLSCHAFT Figure 4.

Orientation Control of (K,Na)NbO3 Ceramics Using NaNbO3 Particles Prepared by Single-Step Molten Salt Synthesis

“…Because of their high Curie point (T c ) and favorable piezoelectricity, (K,Na)NbO 3 (KNN) system ceramics have been a well-known promising candidate for lead-free piezoelectric ceramics. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Orientation control techniques are widely used for improving the performance of piezoelectric ceramics. [1][2][3]9,10,14,15,17,[20][21][22][23][24][25][26][27] The reactive template grain growth (RTGG) method, in which plate-like NaNbO 3 (NN) crystal particles are used as templates, is mainly employed in the orientation control of KNN system ceramics.…”

Lead-Free KNbO3:xZnO Composite Ceramics

“…As we know, pure KNbO 3 is easily deliquesced due to the high water-absorbing issue. 21,22 In this work, we checked the water-absorbing property of KN:xZnO ceramics, as shown in Figure 9. One can see from Figure 9a that pure KN ceramics were immediately deliquesced as soon as the sample was immersed into water.…”
