Popis: Alkali metals (Na, Rb or Cs) co-doped with fiber- and bulk-shaped KNbO3 single crystals were grown using two original methods by means of doping together of small ionic Na and large ionic Rb or Cs into KNbO3. Single-phase crystals could be grown with an orthorhombic system at room temperature as well as pure KNbO3. Piezoelectric and ferroelectric property changes by the co-doping of Rb or Cs with Na were estimated using d33 values and a polarization-electric field hysteresis curve in fiber- and bulk-shaped crystals.
