Control of the Crystalline Structure and Piezoelectric Properties of (K,Na,Li)(Nb,Ta,Sb)O3 Ceramics through Transition Metal Oxide Doping

3 July 2023/

Fernando Rubio-Marcos, Juan José Romero, José Francisco Fernández and Pascal Marchet Abstract: Divalent transition metal oxide doping of lead-free (K,Na,Li)(Nb,Ta,Sb)O3 piezoceramics is studied. Two different behaviors were observed independently of the doping metal: at low concentrations, the tetragonal structure is preserved, while at a high doping level, the material becomes…

Piezoelectric fiber optic modulators and micro-tubes

3 July 2023/

Glen R. Fox, Claude A.P. Muller, Matthius Kuhn, Nava J. Setter, Nguyen Hong Ky, Hans G. Limberger Abstract: Miniature all-fiber phase modulators have been fabricated by integrating piezoelectric actuator coatings with telecommunication optical fibers. Evaporation and sputter deposition processes were used to grow thin film PbZrxTi1 – xO3 (PZT) and…
