| Popis: | Alkali metal (Na, Rb or Cs) ion doped KNbO3 fiber single crystals are grown using an original pulling down method, to improve their composition change during a crystal growth, by means of co-doping of small ionic size Na and large ionic size Rb or Cs into KNbO3. In spite of the co-doping, single crystals can be grown with orthorhombic single-phase at room temperature, as well as pure KNbO3. Their electric properties, such as impedance, are changed depending on the doping ions. Na and Rb co-doped KNbO3 is promising Pb free ferroelectric and piezoelectric crystals. |
